To check for vacuum leaks spray "starting fluid" around where the intake manifold bolts to the heads & where the carb bolts to the manifold & see if you find a spot where the motor speeds up, indicating a vacuum leak.

Is it possible the lifters are too compressed & as things heat up the plungers are bottoming out & holding the valves open (long shot).
this can happen when the heads have new valve seat inserts, or with new heads.
