Port match
Should I port match my air gap manifold to suit my heads?
The intake ports on my heads are bigger than the manifold so there wont be any issue's there.The question is will it make a difference if I match them or not?
The runners are a bit rough on the inside.Is it worth cleaning them up? If so whats the best way to do it?
Any of you guys running air gaps what did you do to yours?
