It was interesting how even the HP numbers were considering the fairly large difference in port volumes. I will say that the TW head is deceiving in the fact that the port volume "appears" small. However with the relocated valve, the port is a bit shorter in length and that shows up as smaller, but the actual height and width measurements are quite comparable to the other heads. I was sure the Z304's would do better than they did just from the average of the flow numbers. I guess that's why we don't race flow benches! Thanks Richard for all this work.
I left a comment in part 1 asking about 205 11r heads on a windsor. I see now that the heads are going up in quality/performance in each video. Love the info dump in all of your videos. Very educational and easy to understand with basic engine building knowledge. Thankyou for all your research!
Richard you should do a eBay SBF cylinder head comparison. Procomps, Skip White NBK, Flowteck, and Pro Maxx. Would be great to actually see how these budget cylinder heads actually perform.
Dang, I'm waiting to see them all now, before I choose which ones will go on my street 351w turbo build. Thanks for the information, it's saving me time and money.
I’m glad this test was done with SMALL CAMSHAFT because when they’re done with giant camshafts it really SKUs what the head can do more power with less cam better the head.Car craft may have received the best 165AFR that ever was made lol
I'd like to see where a set of Cleveland heads 2V , Aussie 3V , 4V closed chamber would fall in relation to head flow, tourqe and horsepower in comparison with aftermarket Windsor heads. If I remember correctly I seen a article from 1980's SVO part catalog the factory iron 2V open chamber Cleveland heads and street boss duel plane intake on a otherwise stock 302 H.O. long block was good for a 50 Hp gain.
would have liked to see the summary of hp and torque gains on a graph for each head. All in all a great video and with a lot of hard work changing heads and doing dyno runs. Much appreciated.
AFR heads are magic. They were about 5th best on mid-lift intake flow out of these 10 heads, but had the best peak flow, but past the peak lift for this particular cam. They did have the best mid-lift exhaust flow, but not the best peak exhaust flow. But yet they had best peak power, even better than the higher compression Canfield head, and had probably the best average power. Maybe I should get an AFR tattoo.
Richard , thank you for your years of testing parts . I always enjoyed seeing your articles in MM&FF ECT back in the day . THANK YOU FOR ENCOURAGING HOT RODDERS AND HELPING ANOTHER GENERATION LOVE RACING AND HOT RODDING!! 👍✌
I haven’t watched the video yet,,, But Brodix’s new IK series small block Ford head looks KILLER on paper for the investment. Your video here, and then releasing those heads, might just push me over the edge on finishing my 331 build,,,,,, If only i can find a set of short rods...
Sometimes the best head is the one you have. I have older twisted wedges, stud mount I got used, with 1.7 rollers on stock SD cam. Runs quite strongly in my light fox with a 308 bottom end.
@@richardholdener1727 running speed density efi and a crane interceptor 2 for tuning. Remember that thing? It's been on a shelf in my house for decades.
Great comparison Richard. This is the kind of detail everyone hopes to see. I especially welcome your comment at the end about how all the heads perform well enough to satisfy most hot rodders needs, and the down-to-earth cost consideration. Not everyone is competing at the dragstrip. With that in mind, how do you think the budget ProMaxx 180 SBF head would have performed in this line-up?
I have the Promaxx 180's on my 302 and am very happy with it. I'm going to a 331 stroker now and I really don't need to change much. I have been considering upgrading the cam. Good luck
I like that are you comparing them to most hot rodders that just buy the heads off the shelf and bolt on and go. Would also be cool to see you grab say your top 5 and give them the most power output possible. I know you did these a long time ago but still awesome to see
I just uncovered a forgotten set of 351 D10E heads off a 1971 Bronco that I had stashed in the garage for 25 years. Guess I'll have them blasted, magnafluzed, re-valved and build them ...then store them back in the garage.
GOT A SET OF CANFIELD 192CC HEADS ABOUT 10YRS AGO FOR $600.00. COMPLETE WITH FORD RACING ROCKERS AND FERREA VALVESPRINGS. GOT THEM ON A 308 WITH THE XE274HR CAM AND GT40 TUBULAR INTAKES.
@@iqinsanity Would be helpful for me. I suppose if it were too confusing for someone like yourself, you could easily just ignore that part of the video.
Lol, you think it would confuse me? I’m not the one who can’t pick a head without a graph with 10 different lines on it. Maybe you should just buy a pre matched package? Edelbrock and Trick Flow make nice ones for amateurs such as yourself.
Ten curves laid over themselves...youd see them all together but you wouldnt really be able to differentiate the curves. It would just be a mess. Like was said...screen shot and stop being lazy.

I love the work you have did and doing. Now I am going to ask a question that may be stupid to some people but here goes. All of the heads liked the mid to upper rpm cam. But with current fuel prices, are any of the heads good for low end and fuel economy with a little bit of fun?
I am currently assembling a 331 stroker motor ( with X303 cam) using World Products Windsor SR heads. Will you be evaluating those in this series? Just wondering if I need to open up the ports a bit before bolting them on. Thanks for all the info already provided and in the future.
You guys need to audit a university fluid mechanics class. It'll give you more 'tools' to understand how/why fluids change their flow characteristics. There can be a lot of math to fluids, but just understanding bernoulli's equation and the continuity equation only needs algebra and explains a lot.
No mention of Reynolds? 🤔 Bernoulli is idealized. Intake port dynamics are not. What youre suggesting takes a whole .003 seconds to find on youtube...no need for a uni.
@@richardholdener1727 I was thinking between you and the guys on engine masters. Not being a troll, just suggesting ways to get more 'tools for the toolbox' and better understanding. Bernouli will explain the interrelation between port velocity and pressure, and continuity equation will relate cross sectional area to velocity. There are other ideas like headloss equations and discharge coefficients and yes Reynolds, but they get a bit mathy.
I heard tell of in the 90's a lot people put on 289 heads. raise compression around .9. If it was 9.5 pistons. With the heads on it. Be 10.4 in 1. Something like that. It was custom i think.
The flow bench tells part of the story, but the dyno writes the final chapter! Looks like AFR does their homework a little better than most, another win. Especially significant when they spotted Canfield at least a couple percent on the compression due to chamber size, maybe 10 hp at this level. If I still had my ‘89 5.0 notchback I know which way I’d be going thanks to your endless energy, Richard!
Mid flow exhaust determines power potential. Add a 1.7 exhaust valve to any head watch power climb if you can’t pressure out u can’t get the air in to make power
Have you ever tested the Ford Sportsman cast iron head. Years back rumors said the brand x guys were complaining because these head were outflowing anything from GM? I know they use an unusual exhaust port layout not used by other sb ford heads.
@Richard Holdener This is probably a question you've gotten a ton, but I'm going to try anyway. I have a stock low miles '92 5.0 that I'm going to do H/C/I. I plan on using your favorite Comp XE274HR cam, and probably a well ported Explorer upper/lower intake. My question is regarding heads. I would like to go with something like an AFR #1450 (205cc intake port). However, AFR's own literature about the AFR #s 1399/1402/1472 (165cc intake port) says: "They feature 100% CNC ported intake, exhaust & chambers, A356 aluminum castings and high quality components throughout, in addition these are the only AFR heads that are compatible with the OEM piston valve relief." Is this true, or are the AFR guys full of it? Will I have to have the pistons fly cut or replace them to run anything with a 2.08 or 2.02/1.60 valve combination? I assume you've tested a bunch of these so you'd be one of the best to ask this question. Thanks in advance. Brent
@@richardholdener1727 Wow, I got a reply with some GUSTO - and FAST.

I do realize the 165 is an excellent head, particularly for a stock 5.0 short block, but it would be nice to not have to buy 2 sets of heads....kind of along the same lines as how your "favorite cam" works well on such a wide variety of applications.

When do you need to start considering race gas in this kind of combination, or in 351 Windsor? At what compression ratio do you typically need more octane than pump gas?
That is a very common question people have . Too many variables for a blanket comp ratio. Your camshaft makes the most difference. Static compression and DYNAMIC compression matter . Run both specs on a calculator to see where you are. The general consensus is 8.5 to 1 or under dynamic compression or under 180psi cranking compression is pump gas friendly. I have a true 10.55 to 1 in my Windsor on my channel on pump gas , i have pretty large cam specs though.
@@deanstevenson6527 Running over 210 psi for years on 91 octane pump gas , way too many variables to say everyone can do it or should do it . That's why i said to keep it under 180psi

Awesome video! Loved seeing these tests in the old MM&FF and others back then. I do have a question though. Did you ever try running 1.7 rockers at any point with the 274 HR cam with the 333ci? How much would that effect the duration and lift? I actually have a nearly exact build about to go in my 86 GT, 333ci with 274hr and 1.7 rockers, AFR 185 Outlaws( I think same except emissions) and a TFSR intake. Curious how much difference the 1.7s could make...

hi Rich love your video, im running a stroker 351c with the original quench chamber 4v heads , was thinking of up grading to aluminum aftermarket , do you have any tests on these ? thanks
I want to see a Ford 302(stock stroke) with a max hydraulic roller cam. Head test showing the AFR 165 heads all the way up to the AFR 225 heads. I am willing to bet that the 302 with the 225 heads will make the most power. Victor manifold, Holley Dominator carb, 11:00 to 1 compression, pump gas. I think people undersize their heads on the Fords too often. Bone stock 6.0 lq4 makes more power with the square port heads than the cathedral port heads.
Hello Richard! Thank you for these videos! I will be using the same comp cam in my 331 build and I have a question. What distributor gear are you running? All info on line and even from comp cams support conflicts, with people saying steel, bronze, composite, melonized, etc. Hoping you can help with real world knowledge! Thank you for any help you can give!
@@richardholdener1727 thank you Richard! For informations sake, do you know what material these are made from? I have an old factory distributor, but I have not checked the condition of the gear... I have a new distributor coming with a steel gear that I will need to change out if this will not work. :)
You know I have to ask: With the battle between the TF and AFR guys still strong, what size TF heads? 170? Those AFR 185 heads really impressed with good power.
@@attitudeadjusted9027 my point is I think the Cleveland heads have bigger combustion chambers they were a canted big valve head and used different pistons
The Edelbrock and AFR heads, were they as cast or factory CNC ported? Getting ready to make a purchase and want to know If I need the CNC porting which is about double the price.
I "inhereted" a hot 88 Mustang due to a suicide. It has World heads but they appear to be cast iron. Any clues to what I have before I tear it down? It runs great when the computer and fuel pump cooperate. Which is not very often.
@@richardholdener1727 Ok, thanks. The special headers were a real pain in the ass but really unleashed a lot of power versus the unequal lenght short tube ones. My seat of the pants dyno says 40 more hp. My seat of the pants runs a lot of aircraft engines so I know what each HP feels like. I can feel a 5 HP difference.
It’s Interesting to see the dyno numbers on the 331 especially when I’m an owner of one though I did not use any of these heads. I was expecting the same test being done with the same 306, kind of a bad comparison as it’s not the same engine. I imagine the next test coming up will be bigger heads and a 351 and the test after that will be even bigger heads on a 351 stroker. Kinda hard to compare all the heads and not have the right data for a 302. Still interesting to see just a little disappointed. I imagine it would take a very long time to run all of these heads, take em on and off, on the same 306, then do it all over again in the 331, and again in the 347, and again in the 351, and again in the 351 strokers but that’s to only way to get an accurate data. Thanks for pointing out the valve spring issues now I know what heads need spring upgrades.
@@richardholdener1727 how do you determine what heads shouldn’t be used on a 302. I know there is such a thing as too big but how to know it mesure that?

Run both specs on a calculator to see where you are. The general consensus is 8.5 to 1 or under dynamic compression or under 180psi cranking compression is pump gas friendly. I have a true 10.55 to 1 in my Windsor on my channel on pump gas , i have pretty large cam specs though.
Cold cranking compressions above 180 psi at sea level will need 95 octane.
@@deanstevenson6527 Running over 210 psi for years on 91 octane pump gas , way too many variables to say everyone can do it or should do it . That's why i said to keep it under 180psi
Did the intake match the head ports or did you need to work it?
TWISTED WEDGE STILL GOOD
Why would someone dislike these videos
They’re probably butthurt that their fav head didn’t do so well.
LS guys
Uhhhh. I want those old Canfields. ....why doesn't someone make a really small chamber in a sbf head? I want to do a budget stock long block max effort ho engine. I have a set of gt40p heads I may mill or even angle mill.....or drop the big bucks and do 11r's
@@vrm86gt Sweet! How did I not know this......Now if only they would go on sale for 50% off!
best man for the job
No flo tek? :(
What size cam do you recommend for the street with a 331 stroker with max lift of .600 ? im running 219/219 howard's with .578 lift with 1.7rr's
224/232
Mid lift flow. Yesss!
Thank you Richard.
Welcome!
Do you think those apr 185s would work well with a lunati voodoo hydraulic roller 282/290 on a 331?
yes
@@richardholdener1727 awesome thank you hopefully it all works out cause at altitude here in Denver but it's also going in a 2400 lb car so should fun thank you
Awesome video! Loved seeing these tests in the old MM&FF and others back then. I do have a question though. Did you ever try running 1.7 rockers at any point with the 274 HR cam with the 333ci? How much would that effect the duration and lift? I actually have a nearly exact build about to go in my 86 GT, 333ci with 274hr and 1.7 rockers, AFR 185 Outlaws( I think same except emissions) and a TFSR intake. Curious how much difference the 1.7s could make...
they add lift, about 2 degrees of duration-sometimes add power
i really liked this one.i guess i'm from the old, maybe too old school being 73, it sure looks it could be fun, but i dont even remember what a E7TE-CA is can you HELP . i was by my gnd son and could't help. thanks
e7te heads are the 5.0L Ford factory heads
Thank you very much. You have a heart the size of Texas. The Lord Bless you are draw you near. In Jesus name Amen 🙏. Your a very kind person to make all this content. To help us tks🎉🎉🎉🎉
hi Rich love your video, im running a stroker 351c with the original quench chamber 4v heads , was thinking of up grading to aluminum aftermarket , do you have any tests on these ? thanks
only on the 400M and CHI 3V
Awesome, dinner can wait.
I want to see a Ford 302(stock stroke) with a max hydraulic roller cam. Head test showing the AFR 165 heads all the way up to the AFR 225 heads.
I am willing to bet that the 302 with the 225 heads will make the most power. Victor manifold, Holley Dominator carb, 11:00 to 1 compression, pump gas.
I think people undersize their heads on the Fords too often. Bone stock 6.0 lq4 makes more power with the square port heads than the cathedral port heads.
take a look at the port volume video
@@richardholdener1727 Just watched it, awesome! I'd still do the AFR 225 heads on a 302...because Merica!
@@richardholdener1727 Just don't drive part throttle 😀
Hey Richard on the 5.3 ls with the big comp cam did you use stock 7.4 pushrods or then you measure for the correct length pushrod thanks
we measure but the cam only changes things if the base circle changes
Thanks
Hello Richard! Thank you for these videos! I will be using the same comp cam in my 331 build and I have a question. What distributor gear are you running? All info on line and even from comp cams support conflicts, with people saying steel, bronze, composite, melonized, etc.
Hoping you can help with real world knowledge! Thank you for any help you can give!
A FACTORY FORD GEAR FROM A HYD ROLLER CAM APPLICATION WORKS
@@richardholdener1727 thank you Richard! For informations sake, do you know what material these are made from? I have an old factory distributor, but I have not checked the condition of the gear... I have a new distributor coming with a steel gear that I will need to change out if this will not work. :)
You know I have to ask:
With the battle between the TF and AFR guys still strong, what size TF heads? 170?
Those AFR 185 heads really impressed with good power.
THE TFS TW PORT VOLUME IS LISTED
What do you think of the NKB heads that have come out have you tried them?
I have not
Richard, have you tried the CHI heads for the small block fords?
yes-they work well
If it didn’t lose too much compression I’d like to see a factory cleavland head in this test
Boss 302 heads are cleveland heads.
@@attitudeadjusted9027 I know but there was no boss 302 heads in the test
Australian 2 Valve is where it’s at!
@@attitudeadjusted9027 my point is I think the Cleveland heads have bigger combustion chambers they were a canted big valve head and used different pistons
@@MissionRestomod those heads are too rare in American
Awesome test
I'm still offering up a 4.9 i6 thats ready for boost if you want to show what they can do
I do but I want to start with stock
The Edelbrock and AFR heads, were they as cast or factory CNC ported? Getting ready to make a purchase and want to know If I need the CNC porting which is about double the price.
afr only came cnc ported when we did this test
@@richardholdener1727 Thank you sir. Keep up the good work, enjoying your scientific approach on all the tests.
Excellent, Great Job.👍
I "inhereted" a hot 88 Mustang due to a suicide. It has World heads but they appear to be cast iron. Any clues to what I have before I tear it down? It runs great when the computer and fuel pump cooperate. Which is not very often.

Ok, thanks. The special headers were a real pain in the ass but really unleashed a lot of power versus the unequal lenght short tube ones. My seat of the pants dyno says 40 more hp. My seat of the pants runs a lot of aircraft engines so I know what each HP feels like. I can feel a 5 HP difference.
Get what you pay for but I seen some fast fox bodies using Canfields and usually 400 bucks cheaper than afr.
It’s Interesting to see the dyno numbers on the 331 especially when I’m an owner of one though I did not use any of these heads. I was expecting the same test being done with the same 306, kind of a bad comparison as it’s not the same engine. I imagine the next test coming up will be bigger heads and a 351 and the test after that will be even bigger heads on a 351 stroker. Kinda hard to compare all the heads and not have the right data for a 302. Still interesting to see just a little disappointed. I imagine it would take a very long time to run all of these heads, take em on and off, on the same 306, then do it all over again in the 331, and again in the 347, and again in the 351, and again in the 351 strokers but that’s to only way to get an accurate data. Thanks for pointing out the valve spring issues now I know what heads need spring upgrades.
His Last comparison was 302 check the last one
the heads were grouped into port volumes-many should not be used on a mild 306-so I made different test motors
@@richardholdener1727 how do you determine what heads shouldn’t be used on a 302. I know there is such a thing as too big but how to know it mesure that?
What about cleaver or boss heads?
YES THEY WORK
Much better chart !!!
Favorite serious period
All you need is boost!
canfield heads back in the day
Aren't the new Ford heads on the crate engines Canfields?
