One of the things I learned in the turbocharger business long ago; air gaps
make a great insulator for hot things. Yes, wrap the starter and if room make
just a aluminum shield that gives an air gap around the starter. You probably
cannot get more than a 1/4" gap but it really worth the effort. Stainless is
better, but harder to work with, Titanium is the best but tough to find and
tough to work. it is a lot easier to say this than to do it, but TRY.

have the starter wrapped in one of those aluminum blankets, and the header
right near the starter wrapped with tape from Pegasus.

the top right of the bell housing, so there should be no reason to bring the
line close to the header - I had a flexible one that just came across the top
of the b-housing from the master. Might be another clutch issue - describe
the symptoms more?
