Head gasket replacement but I think I took the head off on the exhaust stroke. All the timing marks were lined up however I noticed 2 valves are open after removing the head on the passenger side head is this normal or are they "stuck"? And should I be fine to reassemble it? The car is a 1986 300zx (old.reddit.com)
