The only reason i have a D16y5 is cuz i got it dirt cheap and my rod bearings went out on my ZC SOHC VTEC. I still have the head for my ZC and its fully ported and polished. I was wondering if anyone had built a D16y5 with a better VTEC head ? and if so, what kind of head gasket did you use ? As I want to use my ZC head on my D16y5 block, but dont know of anyone who has done it and if it would work right.
