rl Posted February 18, 2007 Report Share Posted February 18, 2007 Need more info, lots more info. Rest of the combo would be a god start. There is no single best head. Quote Link to comment Share on other sites More sharing options...

rl Posted February 18, 2007 Report Share Posted February 18, 2007 Whats the goal? Quote Link to comment Share on other sites More sharing options...
Buckeye1647545503 Posted February 18, 2007 Report Share Posted February 18, 2007 Bang for buck = Gt40-p's Or Afr 185's but they cost more Quote Link to comment Share on other sites More sharing options...
Dave1647545494 Posted February 18, 2007 Author Report Share Posted February 18, 2007 Whats the goal? its a nice weather driver, limited track duty, I just want to make more power with what I have by only adding heads and reusuing the rest of the parts I already have Quote Link to comment Share on other sites More sharing options...
rl Posted February 18, 2007 Report Share Posted February 18, 2007 its a nice weather driver, limited track duty, I just want to make more power with what I have by only adding heads and reusuing the rest of the parts I already have I'd stick to a small head, the cam will be limiting (it could make a lot more with a custom grind) but I would use a AFR 165 or a ported GT40 iron.

Golden Goat Posted February 18, 2007 Report Share Posted February 18, 2007 Edelbrock performers or aluminum GT40's. Don't get anything cast iron, they are literally twice as heavy. These heads are inexpensive and they would take 50lbs. off the nose of your car. Quote Link to comment Share on other sites More sharing options...
rl Posted February 19, 2007 Report Share Posted February 19, 2007 Edelbrock performers or aluminum GT40's. Don't get anything cast iron, they are literally twice as heavy. These heads are inexpensive and they would take 50lbs. off the nose of your car. The cast iron GT40's are a lot cheaper (they can be had for ~$300), flow the same, and are less prone to detonation so they tend to make a little more power, which is why I suggested them.

Bam Posted February 19, 2007 Report Share Posted February 19, 2007 I've got basically the same mod list and I've got the performers, except I'm carbed. 90 block, e-cam, performer heads, performer rpm intake, holley carb, longtubes, all rollers, other smalll stuff i can't think of. I'd love 350whp off spray but no clue. Quote Link to comment Share on other sites More sharing options...
