Which cylinder Heads should I get ?

You need to be brutally honest with yourself. Street car or Race car.

Street car: I would stay with the edelbrock heads since from what I have seen they seem to make a consistent and powerful combination with the parts you already have.

Race: I would lean to the Canfield/Yates etc...requiring race fuel and high compression, high RPMs and really stout shortblock $$$$$$. Would you really want $4 per gallon fuel in a street car?

What ever you do I am sure you will make some big power, Good Luck

 

Being that your other components are edelbrock I would stay with Edelbrock.
Actually you should call Edelbrock and tell them what you want to do and have them tell you what you need to do to get there.
If this build was from scratch and you were wanting a street car that very few others could touch I would say the Canfields hands down.

 

Hey MAVMAN. What on earth is a Flying Toilet on a engine.Iv'e never heard of that. is this something special to the USA only.haha

 

You can mix and match parts just fine.
Heck, Edelbrock parts aren't Edelbrock parts most of the time.
The cams and valvetrain are TRW and available straight from them or Summit sells them as their house brand.
The carbs are Federal Mogul AFBs.
The only thing Edelbrock does for itself is cast aluminum.

Sorry I didnt tell the whole story of what I am planning. I am only putting these heads on for a short time. I am going to buy a 408 stroker short block from DSS Racing and put these heads on it. I just want more out of my 302 before I dump it.. although it has only 30,000 on rebuilt motor. So I was lookin towards the AFRs or canfields. This motor on pump gas will make well over 500 horespower. It will be around 9-9.5:1 compression, 500-600 lift cam etc etc... its gunna just be a weekend/drag strip car. I was thinking of the Ford racing R block but decided to go with a dart most likely because i've heard horror storys with the R's . Anyway back with the lil 302, i'm just lookin to have around 300 horsepower or so with a new head cam intake carb swap and looking to spend no more than $2000.... I'll prolly buy the RPM intake AFR heads, some headers that fit " anyone know of any ?" and a comp cam perhaps.

Thanks for your help.. any other ideas ?

Nice guy, and honestly the best customer service I have ever received...from any company bar none.

 

flying toilet............thats what we call it when you have held it as long as you can and there is no choice but too..."fly to the toilet" :bananaman
Actually its a fuel delivery system.....I am not real familiar with it other than knowing that alot of racers run them........I think they improve e.t.'s over carbs and are dead on consistant once you get it right!

But Todd will give you the true low down on it!

 

You don't need fancy aluminum heads to make 300 hp with a 302. Mildly ported GT40's, Gt40P's, or even early 351W's will get you there.

 

Diversified Products Marketing is advertising GT40 Aluminum Heads in the latest issue of 5.0 and Mustangs and Fast Fords for $699.00 a set.

That's cheap. start with them and get out the die grinder.

 

With the right parts, 300 is attainable with 289-302 heads.
Been there, done that.

Well where does one start?
If you are going to run these heads on both motors then you can forget the Yates heads but CometGT1974 is right about what he said about them.

Bang for your Buck?

Most Hipo shops that port heads have found that they can get very good numbers on both the int and exh with a 3 stage Victor Jr. 330 int and 225 exh.

I'm hoping to find out what the copy cat Victor Jr's will do this off season when I have more time and money. Now if you don't know what I'm talking about then follow the link below to see and for the price I just have to buy a set and see if I can get the same flow number as the Jr's.

Your 408 to run will need to breath, if you don't put a good set of heads on it you've wasted your money buying it!

CNC and Stage III porting will make that 408 come to life!
If you have the room Super Victor intake to top off your heads!

On the 408w...
I have been mulling this over and going back and forth between a couple of heads.
I keep coming back to AFR 205s everytime.
When I compare, I find that in order to get a bit better head, the price goes up dramatically AND almost invariably the exhaust ports are moved drastically.
We all know how tight the W is in our cars and the limited availability of good headers that will match the performance of one of these high end heads.
Weigh the cost of raised and re-patterned heads combined with cu$tom headers to AFR 205s with Hooker swap headers and I think you will see what I mean. Custom headers will cost big bux!
The AFR 205s flow awesome, even compared to some of the relocated heads, but the exhaust ports are only raised 0.125" (1/8"), I can't see that being a problem for off the shelf headers, that is nothing. They also accept standard flanges.
I would suggest 225s, but they are raised 3/8"... header problems would start getting iffy there. I think they are Stahl pattern as well.

FYI: AFR 205s get up to 310/235 for flow out of the box, before any 'stage x' porting expense.

 

yes but I want to put these heads on my race motor in a few months

 

I have the 205's on mine....would not trade them!
Luv'em to death, great power all over the rpm range.
