what did you end up getting for a cam?

dont need all that much clearance for dyno work, especially if you have plenty of spring..

i had a 383 Chevy i was doing some cam testing with, and one of the cams i tried had about .035 intake/.050 exhaust clearance.
no issues.

i know some of the SS guys routinely run around .030 clearance on the intake side.

dang them NHRA class racers.
