what would be the head recomendation then for greatest hp/tq gain?
for the best price because i know AFR heads are really good but there very expensive

 

the best heads for a streetable 302 would be either

a) AFR 165's
b) Canfield 170's
c) Trick Flow Twisted Wedge

there is great debate between these three heads, all of them will give you a substantial boost in HP. if you want something more exotic for the WOW factor plus great HP gains, the aluminum cleveland heads and matching intake from CHI would be most excellent and you'd basically have a improved version of a BOSS 302

 

racingheadservice.com (a comp cams company) or edelbrock victor jr heads and get a 56-60cc combustion chamber so you dont kill your compression...

 

I do not think you are asking a complete or correct question yet.

You have to consider the whole package to get the greatest gains. You should start with intended use of the car, transmission and rear end gearing, and other modifications to the engine to determine the "best" heads. For example it does not make sense to use expensive high flow heads unless you have a matched cam and exhaust system. Then to get the most hp you need to spin the engine to high rpm which means you need a good crank, bearings, rods, pistons and rings.
About the time you're getting the most out of the engine you are over stressing the transmission and rear end.... The list goes on...
Things are starting to get expensive... how fast can you afford to go?

 

Good point, I would plan the project as a whole then make a decision on what heads and other stuff. Good looking ride!

 

hey you should buy those 4v heads that were on here a week ago i mean 4 valves to a cyl that insane well on an older engine like that and if you don't like it jsut give me the the heads i'll put em on my 289

those heads WERE sweet

 

Interesting stuff - but I'm always leary of using parts designed and assembled for a few maximum power pulls on a dyno (or for racing for that matter) as the basis for a street engine. But it does answer the question about getting the most power from a pump gas engine.
