I had read a bunch of articles that say do not polish the intake port... so? how do you port it with out polishing?

do you just leave it rough after porting for atomization?

im confused!!

Port to your hearts content, just don't make it mirror smooth like you would the exhaust.

What gives more help to flow, back cutting valves, pocket porting to the valve guide, or cutting the valve seats? Will a polish on all three above add enough to tell the difference? Have been running totally stock head and are allowed to pocket port to the valve guide. BIGG C
