well i see it is not all the machine shops problem they did what you wanted it just did not work.i would of still did them my way and tell you what you can cut in water so this would not happen with smaller seat od or less chance. sounds like to me they were over ported by some that did not know much there not much iron in the bowl on the stock head i do not go nuts in the bowl get very thin when cut out for 1.880 valves . they may pour sealer in the head but it will not make a better head so if there is no iron were it needs to be sealer is not going to stay. like to see were they are leaking but not seeing them i just would not use them you will blow the bottom end up if they come loose .you will not see much i think with your cam if the heads are not use do your self some big problems buy a iron head like darts or merlins .i would not use your head in on a boat
