2 destroyed starters in a row...WTH?

It sorta looks like the pilot in the bell is mangled.

The pilot-hole in my 1970 M/T bell,was too large to properly fit/support the pilot on my mini. I knew that could be trouble, with an 11.3Scr/185psi cranking pressure, so I installed Belville-type washers, on studs, and hoped for the best. That was 1999, and so far so good.... altho after the last teardown and cam swap in 2004, the pressure was reset to 10.95Scr/177psi.
Idle timing on my 367 is 14*
