340 Rear Main Seal Install with Superformance Seal?

Not a machinist by any means, but for those wondering about putting sealer on a machined surface, I can tell you that from my shipbuilding career, I know that Naval steam turbines are metal to metal surfaces on the casings. There is no sealant used. "Scrapers" (a dying art) spend many hours mating the casing surfaces on board the ship, but no sealants are used. Just my 2 cents.

used to do the scraping thing on pipeline engine bearings , always hated it ! Hated grinding the poppet valves for the compressors too !
nothing between the caps and case, those pipeline engines set in place and run for 40 or more yrs . some times . they can change oil and coolant in them w/o a shut down.
