What is the flow difference between the two. I assume the 113's have a D shaped port. However does anyone have a flow bench comparison. Yes I was aware that the D ports flow better. If I can find a set, they would need the port work, which would probably cost me money because he has already started on my heads, so doing two would become more.
Would it really be the matter of a second off my ET's. Just out of curiosity, I notice that those vettes are only rated about 20 hp more then mine. Or is it a matter of the more mods you have the more apparent the d port head is?
