440 Source Super Stealth, what flow #'s?

Okay, we pulled the trigger on a pair of Super Stealths today, they'll be here next week. Its time to see what these heads will flow. We'll slip some valves in and do some OOTB flows, then work them over and see where they go.

If they really do have more potential than the Stealths, they should be a very interesting cylinder head. I say this because we have a test Stealth head here in the shop that is producing these flows in different intake port configurations.
