Porting Mopar 318 smog heads.

What exactly ate you going for here, you're milling and polishing away...depth checking shallow/quench side of the chamber...are you trying to use some custom quench dome pistons...what are the final flow numbers??
I have had so many people bring in their works of art all shiny and uniform and once they settle onto the flowbench flow not half as good as they look.
Looks are very deceiving in this biz.
