Hi Troy,

Normal things I can think of off the top of my head to restrict higher RPMs are, fuel starvation, air flow inadequate, timing, or springs too light ( valve float)

When you say 6 psi fuel pressure, is that while making a dyno run or at idle.

If 6 psi is steady during run, and float levels are set correct, that seems OK.
Rpm Manifold will support 6K+ no problem.

Springs or distributor?

What brand and model distributor are you using?
I have little knowledgeable how much lift Edelbrock RPM Heads will support, as I never used a set. 532 lift doesn't sound excessive.
