and was wondering if anyone knew the forumla to convert from power to flow rate of the heads. I would like to see what the heads are flowing at, since I did the alot of work myself. Do you use corrected power or actual power?

John,
There are formulas to determine approximatly what power a certain head is capable of which assume everything else is right but you can't go the other way.
An engine dyno equipped with a "hat" can measure total air flow into the engine which can be used in part to calculate fuel ratio among other things but this is not the same as static flow on a bench at 28 inches.

Forgot to mention but nice torque curve

Don't be concerned with the AFR numbers, they are typical calculated acceleration test numbers.
It will actually be richer than what it shows by quite a bit.
