I was just curious as to what the main differences between a performer intake and a performer rpm intake are for sbc. When looking at the two next to each other they are very similar except the rpm is slightly taller. Are the runners the same size? Lets just say you were to put a 1 inch divided spacer on top of the performer, would that basically make it equivalent to the rpm?
