Finishing off the Heads

i just picked up a set of RPM heads, bare. I have a couple questions. First: what is a good, durable, high quality valve set to have installed that'll last on the street and pro-touring, auto-x etc?

Second question: will any mopar big block valve spring work with these heads such as the springs that come with the cam kits?

Combo listed below:
440 block, .030 over
L2355 forged pistons
Decked to .05
Compression ratio around 9.5:1 to 10:1
Custom cam grind with a 507/510 int/each lift.
Torker II intake.
