if your carefull you can get decent results out of a set of PORTED cast stock pontiac heads , youll need to do the typical mods like opening up the ports to the gaskets and blending the combustion chamber edges to the head gaskets and narrowing the valve stem boss,ETC.

(they won,t work nearly as well as the edelbrocks)

BUT YOU CAN REACH THAT 400HP LEVEL.

THE INTAKE AND BETTER CONNECTING RODS ARE JUST ABOUT MANDATORY, THE STOCK INTAKE IS RESTRICTIVE AND THE STOCK RODS ARE WEAK

 

good replacement rods are cheap and easily twice as strong as stock rods

this intake is very noticably less restrictive

getting the compression up to 10.0-10.5:1 and useing the better rods cam and intake makes a VERY noticable improvement, pontiac respond to high compression,good intakes and the combo of headers and cam matched to that higher cpr...they generally WON,T MAKE good power over about 6000rpm-6500rpm and pushing stock rods over 5800rpm is a good way to have a large oil leak where the block failed to stop the rods exit trajectory
