my question is ist possable to put a y8 head on a z6 block, cause the engine currently in my car is a z6, but looking at pics online, the head looks like this (ignore the manifold, but look at the lost motion assembly) but if i look at the d16z6 engine i just picked up, the head looks like this(not my head) (if you look at the lost motion assemblys, on the z6 it sticks out, and on the y8 it is almost covered)

is it possable, anf if so, why would some one do it?

 

Anyone?

 

its possible...but whats the point?

 

yeah it possible, maybe someothin in the z6 head got screwed up and you need to replace it, and all that was available was the y8? From what i heard the z6 and y8 heads are very similar, so you wouldnt get any perfromacne difference from switching teh heads.

 

im not switching it, but it looks like the previous woner did, maby cause the first one was messed up, im honna keep the z6 head on the new engine i bought

 

When i opened the thread i thought you were talking about a mini swap. I don't know. Anything is possible with some TLC

 

the z6 head breathes better than the y8

 

did not know that, thanks Nail

 

It's also easier to tune, y8 timing = ****age

 

well that part i DIDNT know... thanks
