I agree with you. Will see what the machine shop says. Are the grooves in the Cam bearing ok? And is the yellowish color on the pistons normal? When I disassembled the motor, I noticed a couple of the coolant passageways in the H89 head were clogged with a white substance and the water pump was seized. This motor likely overheated and dont know the extent of any damage, if any. After removing the valve springs, I had to tap out several of the intake valves from the valve guides. All the others came out good and felt snug. Will replace all valve stem seals.
