RDF 2000 T/A

I'm building a Iron Block 422 (4.030 bore/4.125 stroke) and going to put a ATI D1SC Procharger on it. I'm ordering 6.0 heads to drop compression and I can either get 2.08 or 2.05 valves. I've asked a bunch of people and have a whole bunch of different opinions. Which do you guy's think would work better?

Thanks,
