Re: Advice On Mild Head Porting Needed

The cc's in the head are ideally done before and after. reason being the two heads may be different and you can match them up on the skim.
The five heads that I did measured from 28.8 to 29.1
If you look on the "how much power" thread I have given some numbers on what amount of skimming gave me what cc drop.
I use 2 holes close together as you say so air can get out.
