I'm not sure on the power valves but SuperV and I are jetted at 75 front and 89 rear...

I really like running the Holleys with the rear power valve plugged. Your carbs may come with the rear metering blocks blocked where the power valve screws in. And I think the general consensus is that you'll need to be around 8 to 10 jet sizes bigger on the rear when not using a rear power valve.

Dyno, Crazyhorse,
Thanks, I'll probably be picked your brains this coming spring when I attempt to dial it in. I'll see what happens.

Did you decide what to do yet? Time's a'wastin', bub. Spring is almost here, at least as far as your machinist is concerned. One thing no one mentioned to you, now is a great time to learn how to read a micrometer. You can save some time (read "money") by doing some measuring yourself. Things like main bearing bores, big end of the rods, crankshaft rod and main journals, stuff like that. Keep us informed as to your decisions and progress. Of course, you could always bring the engines (in pieces is ok) to west Michigan and let Team Chaos put 'em on steroids.:D
