okay right tools for the right job, gotcha. but please explain why get a z6 im. i was told the y8 breathes better. or am i thinking that the y8 head breathes better than the z6 head

the z6 is from the 92-95 ex/si and it is less of a headache to install than the y8, because its all obd1 already, the y8 is a slightly bigger intake manifold but not much, and if you are going to install turbo the z6 is alot more sufficent,

i plan on doing a all motor set up. y7 bottom end y8 head p29 pistons block guard exospeed cam shaft dual springs and retainers. im going for atleast 12 CR.

block guard on an all-motor setup? Why bother? Also why a y8 head? The y7 head is one of the better flowing heads out there. Sure, it's non VTEC, but who cares. Set it up for high end end don't let it drop out of power.

y not block guard.and i already have the y8 head sitting in the garage waiting. and why couldnt the y8 handle high end.
