Don't try and compress the springs with the bolt. This is per the service manual on my Vette. I would also soak the PR's in oil so they fill (they will bubble) and maybe use a dab of Redline assembly lube where they go in the rocker for the startup.

It is TDC 1 and 6, rotate only 90* then follow sequence untill you finish at 360.
Sequence is 1 & 6, rotate 90, 8 & 5, rotate 90, 7 & 4, rotate 90, 3 & 2. END

When I put my LS6 cam in, I tightened them all to 22ft/lb, rotated it and it made no difference. None of the bolts moved from the previous position.

The rest of the car has been apart also, so I believe I have rechecked all the other work. It was by a speedshop on the board, but I will keep the name private.

I have noticed the same thing on 2 cam installs, seems the springs being compressed have little to do with the torque value on the rocker bolt. Never hurts to make sure though.
