Once you've verified that it's not valvetrain limitations, I'd look at making sure you're not running the small 2G carb, since the 1.25" venturi in most street car 2bbls won't feed enough to let the motor turn any more than that rpm.
Also, what intake is on it?

Loose the cheap Z-28 springs and call Comp or Crane and tell them what you are doing. Compare the springs you have to what they are recomending, maybe you can use those.

I've found the Crane 99893-16 springs are really good for racing. They are oversize, but perfect for flat tappet and hydraulics. They last much better than the z28 type and can be had for around $60/65.
