rollup

yes was wondering somthing like usual. Wanted too ask on what you've heard about porting a hf manifold. I had a friend tell me not too do becasue of the flow it has too be exact same specs on every runner. I figured f-it im goin too port with dremel tool and see what happens, too me I figured it would be better becasue it would flow a tad better why wouldnt it. please leave your opinon thanks

use your exhaust gasket as a guide. no need to go biger than that. i doubt it has to be to exact specs, its for a turbo dam it!
