CPT Spock our Pentastar has problems

Ok both heads are off and seem to have the same fate blown between each cylinder. So now I theorize… I think the issue with the cracked t-fitting or the original plastic oil cooler going bad may caused the head gaskets to fail or visa versa. Either way that’s as far as I’m willing to tear down I’m going have the heads pressure checked and rebuilt. Clean up everything and slap down some new fel-pro MLS gaskets and see if it solves the problem if not then I’m pulling the motor and trans, find a low mileage drive train to through in it.
