I don't know if anyone has done this but i would prefer some info from people that have done this. I just need to know what parts i have to mix and match. Head gasket....Head studs... manifold gaskets Anything else ETC. Anyone feel free to add.

 

there isnt much of a diffrence between the z6 and y8 head ,y are you doing this?

but if your going to do this just use everything from the z6

 

Well there is a couple reasons. I needed a complete head- 1. this was available for cheap. 2. The Y8 head has 1/8in bigger intake and exaust ports. 3. Roller rockers. 4. Smaller combustion chamber. Thats pretty much it

 

the y8 doesnt have roller rockers, only the hx y5 does (i believe). man i got a z6 head ive been waiting to put onto my y7, if only we could trade

 

im running a turbo z6,i port and polished the head with a dremel.its not hard and works like a charm still say id rather have the z6 head

 

see i've always heard that the z6 head flows better but the y8 intake mani. flows better thana the z6 part (ive just had hard luck find a y8 manifold), the only thing thats hard to do is tracking down a p28 and finding the time to run vtec. i wrote honda tunning in november on how to put a z6 head on a y7 block (so if anyone needs a refrence turn back to the exhaust notes and read turbo mini-me of that issue)

 

It is an all around better flowing head. Nomatter how you look at it

 

You have a turbo z6??? what is the entire settup your running. B/c i have a fully built and sleeved z6 block. but the head choice is what i am looking at i already have ferrea billet one piece valves, comp cam, titanium retainers and comp springs. just looking at head either z6 or y8 but either way it is gonna be ported and polished. but the Y8 has bigger ports to start w/
