If you have the $$ try the edelbrock performer cylinder heads rather than rebuilding the old pontiac heads. You will get more power and reliability. The stock pontiac heads dont flow that well by todays standard. You can get torque from the old heads but not much horsepower. You would be limited to probably 375 horsepower with the old heads. Remember there was not much aftermarket support for pontiac engines like there is with chevy which has cheaper alternatives. You can build a 400+ hp sbc for 1/2 the price of a pontiac with less hp. Remember new and cheap sbc heads outflow old pontiac heads by a lot. Good luck with the build
