Of course the old drag way of doing this would be to read the plug strap and see if the discoloration changes right in the center of the bend of the strap...
Todays head designs need less total timing - and todays gas also like less timing.... Of course the only real way to know what it "wants" is a dyno... and timing is far more important for performance than A/F ratios.

I agree with Greg here buddy! When we ran our circle track engines on the dyno, they loved 40*. That was with 043 Cast Iron BowTie heads and 10.5:1. As soon as we tested a better set of aluminum heads on the same short block and cam we were down to 38* total. I think all you are doing now is making heat. Glad to hear it singing! Congrats!
