Air compressor on rockers? What do you have the arms of a 5 year old? LOL
The TQ. Spec is like 25ft. lbs. on reusable bolts and 11 on TTY's...I've done a few rocker installs and never turned the motor to TDC, only thing I do is unplug the ICM (bottom of the coil pack bracket) while the valve covers are off AFTER the rockers are installed and have someone crank the engine over and over to check to see if they all move properly and everything is aligned.
