A combination if the both IMO, the z6 head with the y8 mani .

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

compression ratio.

Designation, Int. Valve, Exh Valve, Head cc's, Stock C/R:
D16Z6 30mm 26mm 34.6 9.2:1
D16Y8 30mm 26mm 32.8 9.6:1

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....
