Rockers install question
When installing rockers, are you able to rotate the crank with a hand tool to get the rockers in the right position to be torqued down?
Breaker bar?
Any handy tricks I should know?
Thanks!!!

I used a crow foot wrench on a 3/8" extension + ratchet and was able to sneak it past the power steering stuff. It's pretty tight from what I recall.
I've also honesty just tightened the rockers down before without rotating it at all and didn't have any issues. Probably not recommended but just sayin'. I got enough threads engaged before the rockers started pushing valves open that it was fine and didn't strip anything.

Easy way to rotate the crank ......
Remove this relay:
Attachment 48338997
Then get a metal paper clip, bend it and insert it into these two pins ... The engine will rotate and not start.:

You really don't need to rotate the engine to install the rocker arms ... just slowly tighten them down to 22 Lb/Ft of torque (don't worry about where each lifter is on the cam lobe)

Spun my LS9 over by hand using a 1/2 drive rachet.
Pull out all the spark plugs and make sure its out of gear.. Will spin easy after that.
I tightened down in "sets" .... each cylinder at TDC
