I certainly feel for you man!

Oriignal stamped steel rockers ordered from Butler this morning along with new grooved balls. The pockets in the Comp Cam roller tip rockers that hold the pushrod tip are much deeper than the stamped steel units and maybe that is causing some binding or pressure but from the way all the pushrods are starting to flare out it seems that a longitudinal force is at play. Rockers binding makes the most sense.
In any case, I did not order these Comp Cam rockers. Maybe they are not correct for a pontiac? I am just eliminating all variables.
