All plugs are out. All followers have been removed. I have not pulled the other head since it appeared to be fine when I tore everything down. I was afraid I might have to pull it. Are there any bolts that extend in to the block that I might be overlooking here that could be hitting on a rod? It seems odd that everything rotates easily until the timing mark is in a certain place. For reference if I rotate the crank counter-clockwise it stops just shy of where it stops rotating clockwise, like there is a bolt or something in the way. Really strange.Are the spark plugs in?
Compression will stop it as it comes up, but it will bleed off in a few seconds.
With the followers out, it should rotate freely; there's nothing for it to hit.
Did you have both heads off? If not, you need to pull the other one.
Somethings not right; don't try to start it until you figure it out.
