yes it can be ran with stock compression. the head work would be very helpful as well with the stage 3.

oh yea duh i just remembered whoever does your head that maybe they give it a slight mill just to clean up the surface and make sure everything nice and flat.

will there be clearance issues if it needs a mill
no sir this is like a minor clean up they will check if it needs to be given a nice shave. to keep everything nice and flat for a nice mating surface. dont trip it will be fine.
