Hmm... So far my attempts to move the rocker towers (up, out from the camshaft, and a combination) has been moving the engine on its mounts with no perceptible movement from the rockers.

Eric, when you said you pried them out, did you have to move them up at all, or just towards the passenger side of the car/away from the camshaft? I imagine getting them back in was equally tough... I think adjusting all the valves for the rearmost three cylinders for maximum clearance may be in order to facilitate this. Thoughts?
