Kevin's right - I forgot you were removing the heads in addition to removing the cam sprockets. Look closely at the exhaust valve guides to see if any have dropped. Valve guide seals aren't very expensive and might save trouble later. If you remove the valves and they don't show signs of burning, make certain they go back in the same location.
