Ok heres the deal i am not thinking if valves in my ZC head are bad im gonna get a Vtec head. I have been reading but i know alot of what im geting is not needed seeing as how i already have the mulit port swap, Will that intake manifold fit on a D series Vtec head along with the header i have for this ZC head? Can some one point me to an atricle that only really gos over what im gonna need to know seeingas how i have An si model 91 hatch along with a ZC swap. I was geting to much conflicting information.
