replacement clutch fitting on 503 help

[redneck_raser]

I'm doing the clutch swap on my 503 using cat secondary and p-85.
Does anybody know what offset to use on the primary when boring a p-85 or purchasing a comet?? so far I've had a +.200" (counter sunk) comet and that made primary clearance tight against engine and the secondary would scrub engine air shrouds at full shift. any specs would be awsome.

If using a P85 a Fuji 550F or older triple XLT/Ultra engine version is preferred since same as 503F crank taper.
