Yes they take the same lenght push Rods,it just the lenght of there respective valves that are different due to the difference in the depth of there chambers.

Valve stem height affects pushrod length. I know delivered from Edelbrock their RPM heads use different length valves for the different chamber design to keep the rated installed height at 1.800" on both.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
