See post #32, it's not actually that bad but I agree on double-checking.
@Chadderbox70 I'd be inclined to have that odd bank cut down another .010-.015". These older Chrysler engines are notorious for having poorly machined decks from the factory. iirc the factory tolerance for compression ratio was around a full point (9.3-10.1 or something like that for HP engines), terrible.
