Im not interested in polishing. Its gonna be a hog job for max flow. Thanks for the suggestions guys

Re: WTB LS pistons for boost
 

still, you need to smooth out the surface turbulence regardless. what good is massive ports if they choke flow?

Re: WTB LS pistons for boost
 

Are you talking intake or exhaust? I have been taught that 120 grit finish is sufficient on the intake side. A polished finish on the intake side will hinder fuel atomization due to being to smooth. How ever polished exhaust ports are good for flow.

i assumed you meant exhaust side
