Y8...because you can use your Y7 dizzy, and you'll have higher compression

z6 = good flow in and out best flowing head

y8 = combustion chamber holds a good CR for n/a applications

whatever suits you best, but i love my z6 head all the way

z6 head with y8 manifold... head gets better flow and the y8 mani slightly out performs but just looks better in my opinion... Just don't forget to plug those cold start assist ports....
