Small block Mopar 2.05 and 2.08 valves.

I usually use Ferrea valves on my small block Mopar Edelbrock style heads and will be buying a few sets. (2.05 and 2.08 plus .100 Chevy). What manufacture are you guys using?
Question, do those 2.05's along with 1.600 exhaust clear the cylinder bores and what about the distance between the valves? I'm wanting to learn more about the performance world of the sbm's.
