It sounds good Gomer, it might be a tad too rich. I like 12 to 12.5:1 at WOT all the way up. It will probably be difficult to get it there. You might try different air jets to lean the upper range. It sounds like the main jets are right on.
You might try 1.25 rockers for a little better breathing.
If you really want more you'll need different heads along with higher ratio lifters. But at that point I'd split the case and stroke it.
Dave, you've got it backwards. It's air fuel ratio, air comes first. A lower number indicates less air as in richer mixture.

Doh. When am I going to learn. “No posting before coffee!”
