Flange is partly broken because I cut off the nut that was attached to it outside of the engine case. I was not able to rotate the nut with respect to the flange and eventually cut it off because the flathead end of the flange was stripped.
Wow... You couldn't hold the center stud while breaking torque on the center nut? Why?

Not starting at TDC is a recipe for disaster. The load from the cams is way too much and overcomes those measley little screws in a heartbeat.

There's one crank position where ALL the cams are unloaded, and that's at TDC.

You will not return the IMS to center withoutbremovingvthe loads from it, so you can't get the flange back on to rotate back to TDC; because you can't center it for re installation.

You now have to re- time the engine from scratch, just like everyone else who pulls the flange at any crank position other than TDC.

I developed the simplest procedure for this, it's been adopted by around 30,000 installers and you never see this post from folks that follow it.
