If you want forged pistons they are about $600 w/whatever compression you want. http://www.sissellsautomotive.com/pistons.html

Offy is a better all around intake manifold for the street.

307 cast flat tops w/4 valve reliefs for added compression, or use 250 pistons & install an early small chamber 194 CI head.
