So I left it in and rebuilt the engine. I noticed when I installed the top guide that there was more slack than usual but it seemed to tighten down OK so I went with it. During startup the chain jumped, messed up the timing and bent three valves. I tore the engine back down and replaced the chain as I should have done in the first place.
Im sorry you had a expensive lesson
