The thing about the z1 head is that it will give super high compression (~12.3:1 CR) because the z1 has a very small combustion chamber and very dished pistons. You might be able to do it with premium gas, which I've been considering, but Iono. Anyway, yeah, mpfi, dizzy, ecu, la la la.
8 valve goodness will be noted when I get mine done. I just talked to my employer, over the next two weeks I"ll prolly get 125-150 of work time in, so it'll def get done. Just gotta buy the ish, dad's bring my c clamp valve compressors tomorrow,
