I stripped my 340 down today and have discovered a really large chamfer at the top of the bores. It is far bigger than anything I have seen before.
It goes out nearly to the 4.180 of the old head gaskets.
I guess the 4.080 Cometic MLS gaskets I bought will not be getting used.
Is it standard or has it been done by a engine re conditioner?
