We had a set of (World) double hump heads on it the first go around and the motor ran ok. When we put the Dart Pro 1's heads on we had trouble.

Are you adjusting the rockers while ideling? If so, loosen until it clacks loud, then slowly tighten until it stops...then 1 quarter turn at a time adjust 3/4 of a turn more. Move on to the next (assuming they are hydraulic). You can do this static not running. When the intake in just opening for a cylinder, adjust the exhaust, when the exhaust is just closing, adjust the intake. Loosen until rocker moves free, then slowly tighten until zero lash. Then 3/4 turn further. Move to the next.
Sounds like like they may be solids if you are having the issues you describe.
