I would think if using a product like Yamabond the covers
would reseal, but I’ll take ya’lls advice, and only remove
the “exhaust” cover if all other methods of freeing the
pistons fail. Thanks!

I actually tested the adhesive and heat resistant properties of the Red RTV, several different types of Yamabond, and a couple others. Made a series of 3/4"X2" aluminum plates, bonded them all to another base plate of aluminum. Separated them through a peeling test to simulate a bolt failure, and a shear test as well. Then I reapplied everything and heated everything to 200 F, held it there for a good 30 minutes or so, pulled them out and let them cool and did the same tests.
Pre-heat and post-heat, the Red RTV vastly outperformed any other brand
