In my usual "run what you got world" I would never bother with what RA the heads have... just drive it.
But in today's "perfection" world where everything must be perfect or I can't sleep, I guess I got a little carried away. I've seen so many race motors fixed with garbage can parts (and run GOOD) that I should have shut my pie hole.
Some if my fixes over the years makes UTG look like Dick Landy Enterprises.
