Yeah, the Valiant head/engine looked untouched, head gasket certainly looked OE & was rusted through up front where it should be blocking the hole in the deck...one of those sneaky causes of overheating,.....& I'm fairly sure the Lancer head was surfaced, with the Victor gasket present (.045" thick as removed). If the head had been cut .015", then the 'dime' reference would've been .190" deep, another .010" would probably just clean the cast surface off. So I'd say .200" milled off minimum is likely accurate.
