Stage 1 Porting - ZR-1 Net Registry Forums

No and honestly i doubt there would be a large variance, I had planned on a dyno test but unfortunately I have bad rings.

My stage 1 is not much different than what many consider a full port job. If you are not port matching the heads you wouldn't want 36mm at the head face anyway, as there would be air turbulance from going from 36mm to 34mm(air hitting a wall)

The biggest obstacle is the Inj bosses and I take them out.
