Gentlemen,
Do you know of a high temp epoxy that can be used inside a piston exhaust
port? An exhaust stud has stripped out; it requires a Timesert (or
helicoils) plus the head of the stud extends into the inner port.  Any
experience?

I don't think any epoxy would stand up to that temp.

An option might be to use a high temperature Ceramic Adhesive such as sold
by Cotronics.
