What percentage of the mpg gain would you say comes from the head as
opposed to going all z1?
If I wanted to swap to a z1 head, I would still need to swap mpfi/dizzy/ecu, correct?
labor wise i'd really like to just do the head swap, but either way i have to swap out all that stuff
I don't think the 8valve swap is even worth all the work, what do you think?
