What difference would that make? The intake port in the head is an extension of the runner in the intake manifold.
There are mega differences in the length and volume of the runners in an intake manifold.
CNC `D HEADS ARE THE SAME ---------the reasonthe intake runners should be o equalized , I got a victor down to 15 cfm diff. , and a weiand team g down to 24 cfm diff. , which is a really bad one to start with ------------------and I`m far from an expert !
