I have a 57 buick nailhead that was stuck and now is free, I can turn over by hand all the valves seem to work but one on # 1 cylinder seems to be stuck! one moves freely and the other dosent any thoughts? I was hoping to see if I could get it running! any input?
if it was stuck and now is free I'd be pulling the heads. Especially if a valve is stuck. I'd start with that side and check the rocker and shaft.
