Thanks panic.
I just got back from the machine shop to drop off all my parts and talk with the machinist. We decided on 1.84" intake valves and 1.50" exh valves. He's going to unshroud around the sides of the valves a bit for better flow. We put both a 1.94 valve in and a 1.60 valve in to see how much unshrouding would be needed, and he wouldn't be able to do much without getting into the head gasket area. Since he's been doing heads for like 40 years, we both thought that the slight increase in valve size and limited amount of unshrouding wouldn't be anymore beneficial than just doing unshrouding and using the slightly smaller valves. There would be more area around the valves for flow with the 1.84/1.50 combo. He can do some bowl blending and smooth out the radiuses and get a great flow in conjunction with the lump ports.
This combo will probably work better with the Offy intake too. Might help with some midrange power.
