When I converted a 64 chevy 1 ton (all drum) from a single pot to a dual master cylinder, I added 10 psi residual pressure valve (RPV) from Wilwood to each circuit (the new master had to built in RPVs). 10 psi RPVs keep the springs from pulling the shoes too far back. I think you need them but I don't see how the lack of them would cause the brakes to be grabby.
Also when you say the fronts grab, is it both fronts or does it pull to one side?

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.
