The engine indeed needs to come out and torn apart, as somehow during the process, the exhaust valves on #5 and #7 were bent. I have no idea how that happened. These are brand new Thitek heads. I have never heard of a vehicle being out of time electronically bending valves. I know it is a possibility that the top of the cylinders would need to be notched for the valve clearance, but I would think that would be on the intake side. Anyone have any experience with that?
