Need help getting car to idle.

I can't get my stroker to stay running under 2000 RPM's. When it gets below 2000 RPM, it stumbles a little, then dies. The carb is a proform 750. Float levels are good, I have the idle mixture screws turned out 1 1/4 turns to start, until I can get it running to fine tune them. Primary jets are 75's, and I think the secondaries are 84. I just replaced the PV, thinking that might be the problem, but didn't fix it. I'm going to go check around the base of the carb for possible vacuum leaks now, but it shouldn't have any.

Timing right now is at 30 (locked out on MSD E-curve) (will adjust when I can get it to run)
Cam duration is 237/242 @ .050 with .584/.592 lift and 108* LSA
Edelbrock RPM Air-Gap intake.
Hughes Iron Ram Heads, ported with 2.055 intake valves.
