I am always surprised that solid gaskets without narrow raised borders work. With the various large temperature gradients it is difficult to imagine surfaces remaining flat.
To remedy corroded holes, O rings seem a good idea; one problem is that any significant gas pressure leakage is in the direction opposite that O rings work. Where there is room, fibre rings probably just as effective. but either way the machining is much the same as involved as for a brass insert.
Has anyone had experience with lapped heads without gasket?
