SB Chevy with Pro-Topline 200cc heads, I'm going to use a Victor JR 2972 (Bowtie II) intake but the ports in the intake are further apart than the ports in the heads. I port matched the intake to a Fel-Pro 1205 but have about .100" protruding on each outer edge where the intake meets the head. My question is: Is it better to have the port in the head bigger than the intake, or the other way around.

If at all possible, you don't want to hit a protrusion going from intake to head that will disrupt air flow, so you want the head side to be the same size or larger.
