I can tell the way you talk that your a good guy and i could tell that when i first started watching you. If i ever have to get my heads worked i will be sending them to you sir
I will probably some heads from you for my SBC Just because of this video. Even though I built a flow bench that has 4 approximately 97cfm motors on I that is a floating pressure and had a Hegelson calibrating made. Still fighting it out.
Great content Eric. Very informative. I like the heads, look like great potential. I agree better than using the Vortec heads. Great up grade over cast heads. Thank you, EM.
Hey Erick, I have a really important decision with my motor. It's a bit of an odd combo bc of what it's for. Firstly, this a mud bog truck. Probably 5000 lbs. The motor is a 383, solid roller, 640 lift 250's@.050 duration. 12.5:1 pro topline 220's iron heads. I currently run a dual plane air gap that I ported. Yes ported, not sand rolled. I was thinking bc the truck is so heavy and bc the heads were 220cc's, the dual plane would work well, but now I'm over thinking it. I'm not winning, so I have to make changes. I'm under 6500 for like 1/2 a second. But in second gear. It stays around 6700 for the rest of the run under load. I am thinking about running the super victor but I don't know if it will work any better bc of the rpm under load in second gear
Clearly you love this country and I think that you're right about the family owned businesses. However, I am am going to steal your wrench under the exhaust valve checking spring to keep it from leaking idea.
If you are interested in reviewing a set of Promaxx heads I’ve got a pair of their Maxx series 200cc heads that I’d be happy to let you borrow to inspect, review, and flow test
I got 474 torque and 486 HP out of your ported IK 180 heads with a small hyd roller on a 383. Great heads for the price. I honestly think if he didnt stop the dyno at 6000 it would have been a little higher. Keep up the good work.
Very nice numbers! What did you do regarding the temp sensor? Run it via intake or tap the blank on the head? I'm curious as to what people do when buying these..
There is an adapter I got from summit that goes under the thermostat housing. They make a few of them. I got the one that that will read even before the thermostat opens to be more accurate. Electric fans are going to the intake port.
@@Levisnteeshirt1 he stopped the dyno at 6000. I dont think it would have dropped off for at least a few hundred more RPM. I know the valvetrain and heads would have handled the RPM. The cam would have been the question.
I heard that promaxx does pretty good valve jobs on their heads. you hear anything like that? that would be interesting to see its either those or the brodix st5.0 for my 302 sbf
buy american when ever possible. i'm going brodix after months of research solely based on the fact it is a murcan cast, murcan cnc'd, murcan assembled and probably done by murcan country boys (my favorite murcans).
Have you or do you know anyone that's done a dyno comparison between these ik180's and a set of 461 bumps? I swapped out from humps to these on a 357sbc and I swear it's lost power across the board. Both heads were as cast. 3 angle valve job, done correctly. Same springs, set up properly.
Would like to hear your thoughts on EQ engine quest 220 cast iron heads The flow numbers claimed are really good out of the box. Some small port work and I was able to pick up 32 cfm on intake N 35 on ex. @600 lift Bringing numbers close to ls heads They R cast iron but compared to vortec a reasonable cost choice
He's said several times he doesn't do iron heads , I may be interested in a set of those in the future if you wanna sell em , they do pretty good for what they are
Do you think having a bigger exhaust valve would be beneficial for a mechanical fuel injection motor since the injection cause much higher cylinder pressure? That’s why MfI tends to blow the cylinder wall out more often. So I was wondering if it would help get more pressure out with a bigger exhaust valve?
Does mfi [vs any other fuel delivery] change how many pounds of air consumed per hour for any given rpm? I think not. Now if we were talking nitrous thats different: a bigger exhaust valve would be worth looking at because you effectively have more oxygen available per pound of air delivered - more peak pressure to bleed off so you get proper scavenging instead of reversion.
Hello Eric, I have a question about big block Chevy heads. Have you ever worked with oval port heads? I’ve been looking at the Brodix 270 and the AFR 265. I know that your expertise is in larger flowing heads but just wanted you’re opinion.
I cannot stand Chinese knock off shit! If I cannot afford American made, especially for racing, I’ll do without, or I just won’t run! What really kind of bothers me, is all the great companies who have sold out! Most of the time quality went down & prices went up! If they didn’t just try to have there stuff made overseas! Never mind the prices going up, which costs us more to go racing, just to make the rich, richer! Dart bothers me, because I used to swear by there blocks & heads! I don’t know what’s going on with Edelbrock, but ever since Vic jr died it seems like the asshat that’s running it, is killing it! I know about there move & bullshit, but I dont ever remember ordering anything Edelbrock & not getting it ASAP! We ordered a pallet of Performer intakes years ago, we had about 10 new circle track 355s to build, we also got a pallet of GM cast iron cylinder heads, because we had a engine that cracked the heads, in exhaust & owner wanted new ones! Well we found those heads flowed like 10 cfm more than the old X heads, which is what everyone used & you were not allowed porting! Well we all know how that goes, 😏😏😏😏 I can tell you there wasn’t a sharp anything in our ports! What sucked is all those new heads came from Mexico, but they were all better @ I had to flow all 36 & we used the best ones on our new engines, along with flowing all the intakes! By the time we were done with our new engines, which ended up being a dozen, we were 20hp up! Over the old X headed engines! Remember we could not port or use vortec heads, although ours flowed like they were! 😏😏😏😏😏
These heads are focused towards street use on a 350 [straight up or bored over] and as noted the cam needs to stop stop near 0.500" lift. My instinct would be go no further than 0.540" - but thats me. A 383? Wrong heads, except you setup with a towing cam. Eric catches the spring rate as shipped: might work on a mild roller cam, but really is better suited to solid flat - order to get the spring pockets machined to suit a recommended roller spring diameter.. Somebody running rollers is likely after more lift/tipping into 0.600"+, and without porting, these heads don't serve that - note the approximate wall of 230cfm. These are not racing heads/don't belong on a 283 [on account of chamber width and 2.02 valves]. They are good - but for the intended purpose. Put 20 hours into any 70's casting, and you won't touch these. Work these over? Well, that would be all about intended rpm range, but I think they would edge out the vortec.
I can tell the way you talk that your a good guy and i could tell that when i first started watching you. If i ever have to get my heads worked i will be sending them to you sir
I can tell by the way you type that you probably own a dog house.
Im looking into rebuikding the 327 in my hot rod verse LS junkyard swap. I keep coming back to these heads and the 195cc AFR enforcer as casts.
I will probably some heads from you for my SBC Just because of this video. Even though I built a flow bench that has 4 approximately 97cfm motors on I that is a floating pressure and had a Hegelson calibrating made. Still fighting it out.

That makes me wonder what’s wrong with my buddys ik200 because his ports match a 1205 gasket
The top machining for the seat is about .045 down in the cast chamber surface. How much flow would you expect to pick up by smoothing that edge?
I order a lot of cheap heads and they're almost always like that with the valve sitting up really high.
looks like the valve job you would want for a 100,000+ mile street build

Who owns AFR?
WE LOVE HONESTY
How much would you charge to port a Ford 4.6 2 valve heads?
What do you think of the trick flow power port 190 small block Mopar heads?
I'd check the machine work .
You got my attention now
Would these be a good head for a jet boat engine 350-355 that has a max rpm of 4600 with a comp Xm276hr and performer intake?
Would like to hear your thoughts on EQ engine quest 220 cast iron heads
The flow numbers claimed are really good out of the box.

They R cast iron but compared to vortec a reasonable cost choice

Just wondering how these heads flow compared to dart iron eagle 180cc heads?
So with a 1.94 valve it may flow more then a 2.02 if no chamber work is done ? IE: less shrouded with no chamber work.
It's often the case.
What the price of the brodix ik180 and having them ported
Brodix gives prices on their website.
Hello Eric, I have a question about big block Chevy heads. Have you ever worked with oval port heads? I’ve been looking at the Brodix 270 and the AFR 265. I know that your expertise is in larger flowing heads but just wanted you’re opinion.
I have ported several Brodix 270, I think I have a video of it, they are good. I haven’t seen the Afr 265.
The afr make an easy 560 horse street car motor. Daily driver.
Another great video Eric. I assume the 180 would be a better choice than the 200 for a 350 cubic inch street deal?
Lol, unless you're consistently over 4,500 rpm
What part number for that head?price assembled from brodix approximately and are they available in a 200cc plus version?
I’m not sure on the part number but all run about the same price from me at $1175 plus shipping.
Thanks Eric
US patents do not apply to foreign manufacturers.
What’s your opinion of brodix 18 degree heads for drag racing?
They are good but the port is more designed for circle track. They can be ported more for drag racing.
Generally what is the cost of porting this IK 180?
$1000
Great content!!!
Does that head only come in 23 degree?
Yes

Those heads suck! A mild work over on vortec casting will produce 260 at 500 lift.
That a good reason why I bought AFR vortec heads.
