1000MI and blown HG teardown pics and questions

id check for block deck being flat and true. also the head as well in that area as well.

are you sure all the head bolts had been torqued properly and still to spec torque before removing heads? anything seem out of place as it was being disassembled? loose intake bolts or intake gasket not sealing fully? sometimes these kind of things can be over looked and become issues.
