The end play is set at .015thou. I understand the timming cover may flex a little if the button runs against it.
Correct me if I am wrong but dosnt the turning of the dizzy/oil pump drive force the cam to the back of the block, I thought this is what the torrington on the back of the timmig gear set was for?

On a B/RB/Hemi, the cam is pushed forward. The torrington bearing is useful if your cam end play is run without enough end play and will help to stop premature wear on the face of the block. Otherwise the torrington is almost useless on a big block.
Smallblocks will push the cam to the rear since the distributor is mounted on the opposite side of the cam.
