I must have been thinking of someone else.
More advance will lower temperatures. It sounds like your car was set up for drag racing (4-point harness?). You have a high idle to make up for a lack of vacuum advance. Fix that, and you can lower the idle. Does your MSD setup allow for a vacuum advance? A vacuum gauge will then let you tweak the idle mixture as well. Without knowing what your total mechanical advance is (it should
be 36 degrees, at 3000 RPM), I'd hesitate to make timing changes. A digital timing light with an RPM readout makes this a one-person operation, assuming you have some timing tape on the harmonic balancer.
Good luck! You may want to start a new thread on the timing/hot running issue, as it is likely separate from the temperature-dependent clutch issue, and you'll get a fresh set of opinions. I will say again that my side pipe heat issue was solved completely with timing and minor carb adjustments, following the @lars tuning method.

yep the distributor has the vacuum port
PO may have had intentions of drag racing but not the way it was set up and with the secondaries not even opening up
I was able to set the timing on my big block Buick with the MSD and similar cam and heads so don’t think it will be a problem but will keep that in mind
i think I just need to assume that everything was either done wrong or set wrong on this car and go over it

Do you have the build sheet for the motor? Our shop car has headers that are far closer to the clutch than a sbc Vette with sidepipe headers. While I agree you should get the timing figured out, I have my doubts that the timing is related to the clutch/trans heat issue.
if you start a new thread about the timing for your motor, include everything you can... cam card, installed angle, head specs, actual compression (not just head cc’s), deck height and gasket thickness are also helpful
