I ground the hell out of everything here.

I would also re-examine that heat blanket. Once heat soaked it is no good, worse holds heat! I would fab up a set of heat shields and use them. Air can still cool off the starter between the shield and starter.

Yes, same 00 wire from starter to frame. I can fabricate a nice heat shield and try it in place of the blanket. I do NOT have a ground from engine to frame except for the starter. Can't hurt to try that also.
