Well I have read all the posts on here concerning the backward approach of putting an a6 head on a z6 block. I know its gonna suck on compression, but what kind of pistons should i get, since i am going to turbo it? SRP has got some z6 pistons rated at 9:1 and some for 10:1, should i got for the 10:1 to help make up for the bigger chamber? And, since i got everything apart, should i go ahead and get the head ported and polished? I was also thinking about getting the head milled, i think is what it's called. Thoughts on this please.

 

Check the compression calculator to see what the compression will be. Why would you do this? You have a Z6 block but no head?

 

i had the a6 head already, and the guy i bought the z6 block from said it would all bolt up fine, compression calculator says around 9.7:1 compression with the higher compression pistons.

 

ive heard a6 block is stronger cause of steele main caps or something ill look up on it too see if im right.
