All great ideas Pat, thanks. I wish something would have jumped out at me when I pulled the pan, but nothing looked odd. Guess I am going to have to tear it all the way down and see if all of those items you suggested are within specs. The spring bind should not be a problem as the heads are rated for a higher lift cam than I have. But I want to pull the heads anyway to make sure a valve didn't kiss a piston top.

I'll get those off tomorrow and let you know what I see. I did have it 180 out of time when I tried to restart it and it backfired through the carbs and headers, so maybe I did some damage there.

Pat, thanks for all the suggestions and help, I'll get back tomorrow.
