    maybe...heads that were run for years that still have good seats have a build up of lead that might keep them safe for years. If you're doing any machine work on them, then of course add hardened seats, but if they are runnable as is, the lack of the seats doesn't necessarily mean they'll fall aprt.

    A leak down test should be your next move.
