Forking angles!

So I'm trying to figure out whether my LS swap is going to mate up correctly between the engine, trans, and clutch.

Centerforce has a very complicated approach that measures dimensions from the flywheel flange and the trans face, but since an LS motor has a different flange depth and flywheel thickness it's not easy to apply to my situation. At the end they show a picture of the fork and that it should have an acute angle. So the angle seems to override the measurements.

Hurst's site skips the measurements and just cares about the angle, like the picture below.

I have verified that my bellhousing face to flywheel surface is the same (within 0.02") between the LS and the big block, so I think that's the most important.

But am I safe to rely on the clutch fork angle as an indication that it's set up properly? I have an adjustable ball stud to make it right if its not.
