Okay, so ive been reading alot of topics on here and the interwebs on doing a mini-me on a D15Z8 engine. So basically theres a discussion between D16y8 head, cams, etc and D16Z6 head, cams etc. My question is, which one do i chose? Maybe good to know is that i'm aiming for a max power and torque WITHOUT using a turbo. So what would be the best thing to do:   1 swap a full D16Y8 head onto my block 2 Swap a full D16Z6 head onto my block 3 Change the cams rockers etc. to D16Y8 BUT with the Z6 head
