The factory TRW valve notches for my RAIV head-which has a very shallow chamber as it is more open than 72cc D port and E heads- was really tight on some bigger cams. Even extending the factory angle into the flat portion in the center(there is a shelf on the center part into the relief) helps by about 0.030-0./040. Having extra is probably helpful.
Like John said make sure the rods are correct direction, valve notches since already done at the top and put it together.

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.
