valves

rotating the motor w/o the cct installed will allow the chain to jump teeth on the sprockets and or crankshaft putting the cams out of time. When this happens the valves can contact each other and or the piston crowns. They are delicate and bend easily. Sounds like you need to remove the head now and replace the bent ones. Hopefully only one or two bent before it bound up. It's not difficult to do and is explained well in your manual. Thats the cardinal rule though. NEVER rotate the engine without the CCT installed.
