Vortec heads have 64 cc combustion chambers, if I recall, new assembled
heads are in the $400.00 range through GMPP dealers, I can dig up some links
if you need them.
They also require a special intake, due to the raised intake ports,
Edelbrock has a carb intake for them, price about $180.00 or so.
Also, they don't have provision for EGR....if you need EGR functional for
smog, you'll need to come in off an exhaust manifold to an EGR valve.
