meh, kinda pointless. it will only raise the compression a lil bit and the b16 head flows better until around 8k where it falls off and thew c1 head will carry a lil further. as far as the difference in cams, i know the gsr's are better for boost, but ive never seen an NA comparison done between the too on the same motor.
the intake manifolds are different designs, same with the dizzy and i think some emission stuff.
why do you want to do the swap?
