I stopped the video 12mins in just to make this comment….I was working at Musi with Dave and Tommy Gonzales and I’m happy for all of Dave’s success and even happier he gave Tommy G some credit ….I know this isn’t about Tommy but I’m glad to hear Dave give Tommy his props …..Tommy (a personal friend) doesn’t even come close to getting the credit he deserves in the cylinder head world…..👍👍👍
Dave built the heads for my 800whp STi. He talked me out of installing huge cams (thank god) and gave me an immense amount of knowledge in like 5 minutes. He accidentally full ported one of my heads and then called and gave me a great deal on doing the other head since he made a mistake. So not only did I get an amazing product but also got a port for next to nothing bc he wanted to make it right with me. Headgames is the best around.
@@headgameswhat's the best way to talk to you about a bit of a crazy build plan? I'm sure you've heard about the k48 project. If it gets finished kinda wanna drop one into something a lil crazy. Superlite slc. Issue is on street tires. 700hp is easy. But for actual race slicks car can handle close to double that. Cam and head package is gonna be interesting and probably fairly custom.
Thought ive yet to meet Dave in person, I've studied all of his content for years. Our small online conversations ALWAYS offer me some sort of knowledge I didn't previously have. Dave is VERY good at his craft and his experience shows in his product and results. My FAVORITE thing about Dave is the fact he is NOT afraid to share what he knows. His dedication to excellence as well as teaching are priceless. I love seeing the Alpha podcast grow more each week, and having guests like Dave is a milestone in itself. Keep it up guys!
I was told along time ago by an old cylinder head guy “don’t worry about flow numbers at max lift worry about the flow numbers before max lift because that’s where the valve spends most of its time you are only at max lift for a very short time “
That's the spirit. People spend enormous amounts of money, time and energy to get their cars to certain levels of performance and it's comforting to see guys like Dave are out there actually recognizing this and caring about doing the best they can without prioritizing bleeding people dry for it but rather being clear about what works for specific goals with vast amounts of hands-on knowledge to back it all up. This makes all the difference and they way he speaks says it all. That was thoroughly enjoyable.
You can tell this guy definitely offers his customers cost-effective options. Not one of those shops/guys that bleeds the customer dry. For what he says, it's quite true in many cases as people can over do a head and lose power or have no benefit.
I met Dave at TX2K12, he did a combustion chamber, pocket port, cams, valves, and spring on my ej20 head. I built a flow bench and tested my head compared to another shop. No comparison. My head flows better, everywhere. It has more torque off idle than variable cam ej25s. It simply a better car and has been running strong for 60k miles at over 600 HP. Dave is an awesome person. Dave is an awesome artist. Dave Makes the best cylinder heads and cares to the point where he will talk you out of too much.
Dave Localio and I met way back in 2001. He instantly became part of 2 cars that wrote a lot of Import racing history. Headgames is the first cylinder head to go 6's in Import Drag racing history (6.98 at 196 mph Octorber 2002 Englishtown). Dave Localio will always be my brother, my teammate, and a great Champion! Ara Arslanian
This is exactly why I sent my cylinder head to head games. Dave knows his stuff and his processes are top notch. LOVE LOVE LOVE the fact they measure and ensure all the parts work together and isn’t just an install parts and out the door machine shop. My car is only on break in miles but the car feels as if it just breathes happily in comparison to the stock head.
Great knowledge shared. Loved the whole podcast. I have a zz502 big block. Just curious on any head work that should be done or not done on that create motor. Thanks
The best analogy of porting a head is like sucking through a straw, the smaller the diameter of the straw the harder it is to suck and if the diameter is of the hole is too big you choke. It’s all about having the right combination.
I read GM Hightech performance back in the day! That magazine was awesome! Turbo Magazine back in the 90’s was one of the first to feature even domestic turbo builds.
I have a degree in pro golf management and my old man is a master mechanic and machinist my first memories are helping him build 700+ hp sbc. And the dimples on a golf ball are literally to cause friction and grab the air to allow you to control and stabilize the ball. Without the dimples on a smooth ball when you hit it the ball it’s the craziest knuckle ball you’ve ever seen it will move 20 feet left right up down wherever and not fly very long at all. But to think the dimples actually allows the air to move faster over the all is just dumb. They literally grab the air 😂. The only place it could be helpful is in like a carb spacer to cause some atomization of fuel and air for a moment but any longer then that is a waste and hindering you the fuel can’t atomize anymore without boosting it.
@@kickblake yes. It’s an Applied Arts and Sciences degree based around being a golf pro so everything from accounting, speech, computer software like Microsoft excel etc, irrigation turf management, rules of golf, teaching techniques, cart fleet management and a lot more. I mean I already knew and did a lot of it before college because I had a driving range at my house and did water well work in summers and gave lessons etc. I also built pcs and networked every pc in my entire school and won a state championship in golf so the college stuff was very easy for me but it was fun 🤣.
On the 4B11 topic I agree with Headgames for the most part with oversized valves, those alone won't cut it and the job needs to be done by a experienced shop.I believe you have to go all the way with the head, upgraded springs, guides, oversized valves, cams, and port the head, and have that done by someone with that experience. For example, I have all that done to my Evo X. So fully built head, built bottom end. I have a friend that also built his motor around the same time as me and we have the same builder, same tuner, same parts, stock turbos, only difference is I have the ported head, oversized valves, and guides right. So we wanted to test the theory out on the street. We raced each other from rolls 3 times, and every time from 3rd-5th gear my car was faster by half a car. Then we both noticed that we have different fall offs for our top end acceleration. My friend acceleration falls off at 120 like stock, but my acceleration continues to 140 145ish. Now I know people will argue that the stock head flows better, but at the end of the day if that's true my car shouldn't be the faster car on similar setups it should be the opposite. I'm just throwing that out there, there's paper, tests, and theory, and there's just doing it right. But to be clear, I am currently past that. I'm currently at a level where I am putting that head work to use, and I went that route because on the stock motor, I cracked a piston and snapped a valve in cylinder 1, and I choose to build the head once since I knew where I want my power level to be.
@@luvhcchris at the time the turbos was completely stock, currently I have a open scroll 3591 from Turbos Are US(stock location). I believe my turbine(hot side) is around 65mm I don't have the exact numbers on the top of my head.
@@jonathanbailey646 gotcha. That’s impressive changes to head on the stock turbo makes up that much difference on the rolls, head to head 👌. Lots of other factors like driver mod, etc but if it’s the same result every time, then we can make our own conclusions based off that haha
Even if you say it's faster and he says it's not...... at 1:15:30 he says oversized valves don't fit the seat/head. It's a longevity issue, the valve can't dissipate the heat partially sitting on the aluminum.
@@drewdavis239Saying and doing is two different things. He did say that, no one is out there putting these combos to the street to know if the setups work or not. So things remain in theory, I just proved my combo works. On the point about the valves partly on the aluminum. I'm not discrediting him or anything, but I did say you'll need to bring your head to a shop who's experienced in this, if the valves can't rest on the seats, you can't get a proper seal and you'll see that in your vacuum on your boost gauge. But like I said I'm not going to deny his claim, oversized valve jobs doesn't work for everyone and it's a known fact. I already have 3 years and 20K miles on this head, if I burn a valve then alright. They're only $16 per exh valve, and I can take the head off myself and bring it to the shop. It won't be that simple for other's I'm sure but I'm paying to play and it seems like I'm winning.
Dave is a G! Had them build my 2jzgte head. Gave me insight and dropped some knowledge on me and helped me out a lot, and guided me in the right direction. Much love to Headgames Motorworks! 🤘
Had a cylinder head guy 20 years ago in shady Palm Bay, Florida who did everything at his house. Coincidentally had to replace a 4g63 that he ported into a water line by accident lol
Great Vid, this is guy is a legend! Heard that the golf ball thing was originally tested in rally back in the 80s?90s. Cant imagine that its worth the effort even if it does improve flow a few percent
Smokey was a wild man running 1inch fuellines to get more fuel putting basketballs and footballs in his fuel tanks acid diping bodys having no reverse gear making a 4and half gear
Nice vid. Great info! I'm into the technical aspects of mechanical auto customization and this was enjoyable to watch. Nice set to. Only thing I'd like to suggest is with the production. Maybe try to keep all the participants heads at the same height with adjustable stools. It'll be worth it using multiple cameras and views. Good investment? 🤘
That’s a lot of Information. I was searching terms cause I’m a small block Chevy guy. I was looking up bmw engines, Supra engines. And I’m in North Texas maybe I need to check out a T2k event. Always knew the supra was awesome. I saw one on the dealer lot in 1993. They didn’t market that car well at all. If they would have marketed that car better there would be more. That sequential turbo was crazy. And that’s the 90’s.
I like how he will turn down a job if he knows it will be useless for you. Thus is how a business should be ran. I know you said you dont know much about n/a stuff, but ive always heard from people with sbc bigger valves are better no matter what. Im starting to think ive just heard a bunch of bs my whole life 😂. I think the valve angle,weight and the way the valve is cut back is more important than just having the biggest valve you can fit in the cylinder bore. I loved this podcast episode even though ill never own a import car for racing.
I do think he is wrong on the bmw engines. A bmw S85 V10 i think it was done a 6s 1/4 about a decade ago, so saying he can't imagine a bmw engine ever going 6s is wild 😮
@@headgamesYou did specify the new BMW's. I do not think most people understand they use adjustable valve lift in place of a traditional style throttle body. ( To control the engine rpm.) It's a totally different technology. That technology may or may not be able to function with a spring stiff enough to control the valve, at a power level required to go 6's
Carbs are simple. Air goes through the opening passes over small passages the venturi effect draws the fuel up the passage from the float bowl. Adjustment is all done via jet sizes float level and air bleeds
Because AI is doing all the heads that come out the factory...........Dave is redoing CNC heads because he has 20 years of experience and real world practical application
CNC is also to repeat the same port shape time and time again ie mass production Yes I do agree there over priced [cnc heads ]. What it does show is very inconsistent sand casting at the production line ..
53:40 VANOS and Valvetronic is the reason for the streetability. It's funny, he wants to get rid of VANOS, this is the same conversation as 15-20 years ago when every tuner was scared of VANOS and couldn't figure out how to make use of it, so people were deleting it from S54's etc.
This is a great podcast. Yeah, the hotshots talking shit on brands gets a ton of rage views and rage comments, but this stuff is the meat and potatoes. Respects guys who have smaller budgets, and actually builds cars
Would have liked to hear Tukes ask about the importance of the intake/exhaust manifold …and the effects of boost in an intake/exhaust system …good stuff tho
That would have been a good one! To easily explain it, if you are going to be off, you wanna be off small. To small you know it, too big everyone knows it. Because when either end of that is too large, the response will be lazy.
World class machinist and handsomest man in all of Mercer County 1992. I'd still do him !! 😂 I known Dave since we were kids definitely one of best guys I know back home. Next time I come home I better get a shop tour !!
😂no lie I’m an engine person idc what it is go cart to race car i wanna work learn watch and I’ve seen people do head work and buddy’s work in the lil clip was immaculate
1:12:08 REGARDING RPM AND WANTING A CERTAIN #, I KNOW ON ROAD RACING TRACKS ITS SOMETIMES NICE TO HAVE A LITTLE HIGHER RPM SO THAT WHEN YOU SHIFT IT BRINGS YOU BACK INTO THE POWERBAND..WITH SMALLER DISPLACEMENT ENGINES LIKE B/K SERIES HONDAS AND YES I KNOW YOUR GEARING PLAYS A ROLE IN THAT BUT UNLESS YOUR A FACTORY RACE TEAM ITS NOT ECONOMICAL TO CHANGE OUT GEARING FOR EVERY TRACK...AND WHO DOESNT LOVE THE SOUND OF AN RB REVVING TO THE MOON !!!DEFINITELY THE BEST SOUNDING STRAIGHT 6 OF ALL TIME !
Oh man I just saw this pop up in the feed….. I’m an oldschool lover of headwork from way back in my B-Series days…. Where there were just a few places u could take ur head if u had the money. Were talking oldschool; Dan Paramore, PWK and ofc JG when Papadakis was in the back all quiet just building motors and had much more weight on him. No one knew the secrets beyond 3/5 angle valve jobs and when it came to the actual porting it was like magic and maybe a bit more in our heads than actually making huge power lol. Looking forward to this episode.
Am I wasting my time porting/polishing the headers on my 996 Turbo? The 997TT headers I bought have a ridge in them near the exhaust port on the flange. Supposedly it will help with flow and faster spool. The stock turbos are tiny though!
I don't know what they look like but I don't see how you could remove enough material to really make a difference. And you have to grind on cast iron which is terrible to work with.
Man I feel like people forgot about the Evo X. I remember they used to be called the mini godzilla since it had a dual clutch gear box like the nissan gtr, which were the only two JDM cars sold with that at the time.
I'm about an hour in so you may cover this as you go... The idea that you need big money to make 800 on a BMW is a miss. E36 M3 S52, 4094 It stops being a street car after about 600 though. The CNC is nice in that you can be assured balanced flow between cylinders and no mistakes once a proper program is written. Getting a skilled guy to spend all that time to port/polish your head manually is a lot of hours. I would have loved hearing about how you optimize a head when you have constraints. i.e. How do you max out a head on pump gas? How do you maximize peak while maintaining area under the curve for a rally car where you want grunt and top speed? One trick ponies like drag cars and track cars make life easy. Usually you have to trade off one thing for another. Cams have improved a bit (or maybe its just emissions) and you can buy aftermarket shrick cam that give you improvements through the whole range. I'd love to hear someone talk about custom cams on the platform. B58 is all new technology. The S52 took 15 years for tuners to figure out and prices to come down.
Dying to know. Why measure in CFM? I've always understood its air density that matters. The old 20 psi at 500 degrees makes less power than 20 psi at 100 degrees. There are just more air molecules. Does this same logic apply to CFM? If the air is heated or chilled does it affect CFM all things the same?
I kept waiting for him to talk about the number @50. or like 7mm. you see that number twice during the valve event.. the total lift menas so much less in boosted apps.. this was a good episode,,
Golfball dimples could work... but it would have to be thoroughly researched. You would need the right size and spacing of the dimples for the Reynolds # you're targeting. And they probably wouldnt help in the straight part of the port, or on the far side of the corner. Dimples are turbulators, that can energize the boundary layer and make the air stick to a corner better... so it might be useful on the near side corner, to get air around that radius smoother...
Last time i checked, a golf ball flys through the air. Not the air flying through the golf ball. Nor does the golf ball fly in an enclosed chamber or port! I agree with Dave, a stupid idea.
The only thing a golf ball pattern does in a port, is make a thicker boundary layer and effectively make the port smaller... might help if you have a too big port for the combo and you can't add material.

Yes I do agree there over priced [cnc heads ]. What it does show is very inconsistent sand casting at the production line ..
You see, interviews like this make me flash back to my undergrad, when I was in lecture hall. Feel like I need to break out a notebook and take notes.
This is such a killer podcast! Love what you do man! Having Dave on was such an amazing guest!!
Man I used to be out on woodhaven and the blvd back in the 90’s its was always packed! Like the original f&f
yes! Till F&F came out.
Dave is a very humble dude.
53:40 VANOS and Valvetronic is the reason for the streetability. It's funny, he wants to get rid of VANOS, this is the same conversation as 15-20 years ago when every tuner was scared of VANOS and couldn't figure out how to make use of it, so people were deleting it from S54's etc.
My old man keeps his shop where you would eat off the floor and he’s the baddest dude I know. It’s about self respect.
This is a great podcast. Yeah, the hotshots talking shit on brands gets a ton of rage views and rage comments, but this stuff is the meat and potatoes. Respects guys who have smaller budgets, and actually builds cars
So thankful I found your channel through alex. Love the knowledge I've gained from your videos.
when you guys were saying VANOS in regards to valve lift and spring pressure, did you guys really mean Valvetronic?
Nah, Vanos
Would have liked to hear Tukes ask about the importance of the intake/exhaust manifold …and the effects of boost in an intake/exhaust system …good stuff tho
That would have been a good one! To easily explain it, if you are going to be off, you wanna be off small. To small you know it, too big everyone knows it. Because when either end of that is too large, the response will be lazy.
World class machinist and handsomest man in all of Mercer County 1992. I'd still do him !! 😂 I known Dave since we were kids definitely one of best guys I know back home.
Next time I come home I better get a shop tour !!
💓 anything for you
Gosh!! That intro ALWAYS gets me 🔥...Someone call the Doctor!!
Great info!!! I drive my 2j every where!!!! With a ATF a340!!!
David is the reason I subscribed to this channel
I learned too many people porting go too big Instead of shape. A little shape goes a long way. Even some big names
Turbo stuff does NOT like it
😂no lie I’m an engine person idc what it is go cart to race car i wanna work learn watch and I’ve seen people do head work and buddy’s work in the lil clip was immaculate
I only remember Dave when he was on pinks with the full race crew years ago.
1:12:08 REGARDING RPM AND WANTING A CERTAIN #, I KNOW ON ROAD RACING TRACKS ITS SOMETIMES NICE TO HAVE A LITTLE HIGHER RPM SO THAT WHEN YOU SHIFT IT BRINGS YOU BACK INTO THE POWERBAND..WITH SMALLER DISPLACEMENT ENGINES LIKE B/K SERIES HONDAS AND YES I KNOW YOUR GEARING PLAYS A ROLE IN THAT BUT UNLESS YOUR A FACTORY RACE TEAM ITS NOT ECONOMICAL TO CHANGE OUT GEARING FOR EVERY TRACK...AND WHO DOESNT LOVE THE SOUND OF AN RB REVVING TO THE MOON !!!DEFINITELY THE BEST SOUNDING STRAIGHT 6 OF ALL TIME !
Dave great pod cast. We were the movement. Fun times
yes we were! Thanks Nick!
Oh man I just saw this pop up in the feed….. I’m an oldschool lover of headwork from way back in my B-Series days…. Where there were just a few places u could take ur head if u had the money.
Were talking oldschool; Dan Paramore, PWK and ofc JG when Papadakis was in the back all quiet just building motors and had much more weight on him.
No one knew the secrets beyond 3/5 angle valve jobs and when it came to the actual porting it was like magic and maybe a bit more in our heads than actually making huge power lol.
Looking forward to this episode.
Am I wasting my time porting/polishing the headers on my 996 Turbo? The 997TT headers I bought have a ridge in them near the exhaust port on the flange. Supposedly it will help with flow and faster spool. The stock turbos are tiny though!
I don't know what they look like but I don't see how you could remove enough material to really make a difference. And you have to grind on cast iron which is terrible to work with.
@@headgames ty!
Wait...was Dave known as "The Old One" (TOO) back in the late 90's to early 2000's?
Nope. That was Larry from Endyn.
HeadGames on HT if that is what you are referring too.
Had to stop & hit the like once he said they need a helmet, that’s a window licking moment. 🙌🏽😅
Man I feel like people forgot about the Evo X. I remember they used to be called the mini godzilla since it had a dual clutch gear box like the nissan gtr, which were the only two JDM cars sold with that at the time.
We gettin old dude. Evo 8/9 are starting to become classics. I remember the mid 2000s like it was yesterday.
I'm about an hour in so you may cover this as you go... The idea that you need big money to make 800 on a BMW is a miss. E36 M3 S52, 4094 It stops being a street car after about 600 though. The CNC is nice in that you can be assured balanced flow between cylinders and no mistakes once a proper program is written. Getting a skilled guy to spend all that time to port/polish your head manually is a lot of hours. I would have loved hearing about how you optimize a head when you have constraints. i.e. How do you max out a head on pump gas? How do you maximize peak while maintaining area under the curve for a rally car where you want grunt and top speed? One trick ponies like drag cars and track cars make life easy. Usually you have to trade off one thing for another. Cams have improved a bit (or maybe its just emissions) and you can buy aftermarket shrick cam that give you improvements through the whole range. I'd love to hear someone talk about custom cams on the platform. B58 is all new technology. The S52 took 15 years for tuners to figure out and prices to come down.
This guy is giving us straight facts 💯. Take notes and pass it on.. thanks OG
Dying to know. Why measure in CFM?
I've always understood its air density that matters. The old 20 psi at 500 degrees makes less power than 20 psi at 100 degrees.
There are just more air molecules.
Does this same logic apply to CFM? If the air is heated or chilled does it affect CFM all things the same?
CFM is not the same as mass flow, no.
I kept waiting for him to talk about the number @50. or like 7mm. you see that number twice during the valve event.. the total lift menas so much less in boosted apps.. this was a good episode,,
Gotta search more on the fox body mustangs he has!!!
My Man Dave 🎉❤
Great interview! Meet more people like this guy!
First time I came across this podcast.... Well done friends 👏👍👍
Wow!!! Great pod! Looking forward to some new headgames content too!!
Love this episode, so much great info my head looking like jimmy neutron! Keep it up Tukes 💯
The new BMW and Audi tech is honestly WILD
I need to work for @headgames asapppp. I have a manufacturing tech diploma and 12yrs machining experience. 🙏🏽🙏🏽
AMRY checking in. Great podcast!
LOVE THIS PODCAST! LETS GO DUDE!
Dave head games and Brad from BZE are the goats of cylinder heads
I miss Brad, we used to chat all the time
Tukes youre doing a great job on these interviews brother. Keep it up!
Appreciate it!
Why does he look like the Pawn Stars dude from the History Channel in the thumbnail? LOL. It's a good listen, though.
Golfball dimples could work... but it would have to be thoroughly researched. You would need the right size and spacing of the dimples for the Reynolds # you're targeting. And they probably wouldnt help in the straight part of the port, or on the far side of the corner. Dimples are turbulators, that can energize the boundary layer and make the air stick to a corner better... so it might be useful on the near side corner, to get air around that radius smoother...
Dimples work on two stroke engines especially when you do the crank case
Glad to see the channel growing
shout out to ROute 1 / Roosevelt Blvd / Woodhaven. I grew up by Nabisco
Yes! I miss smelling Nabisco every Sunday night
Back in those days, you’d be 10 YO driving to work at the plant, smoking a cigarette trying to get to that midnight shift.
LSA huge factor in rpm
Ay real talk is bro tweaked of a yerk or what he blinked 14 times the whole interview lol 😂
We need timestamps in the description
Wonder if he's talking about Crower valve springs
Hopefully the GE heads get some love this episode.
GE heads are great. Just tough for old school and bespoke items.
They've been getting loved. What more do you want? Higher prices? Lol
Great content. I followed your page. Definitely keep working on your UA-cam channel. Steve Morrisons started super humble.
Brilliant 👏🏻 really enjoyed that,
Last time i checked, a golf ball flys through the air. Not the air flying through the golf ball.
Nor does the golf ball fly in an enclosed chamber or port!
I agree with Dave, a stupid idea.
The only thing a golf ball pattern does in a port, is make a thicker boundary layer and effectively make the port smaller... might help if you have a too big port for the combo and you can't add material.
I like the intro 😮
My car ran low 11s on 125 shot . 1990 5.0 gt caged suspension FBO cam heads intake.. GATEWAY 50 MUSTANG CLUB I did that stock ported heads. "10s later w dart seniors,
More air+more fuel=more power.
If you want reliability and efficiency, port heads.
Another great podcast!
Wasn’t Dave in an episode of Pinks wayyyy back in the day?
No, a guy from Full-Race and Dave look a lot a like though. 😂
@@diegolp5323 nah I went back and looked he was in the episode with the pink civic vs the rx7 😂
@@diegolp5323 I was just with Full-Race. It was me!
