I recently had a car given to me by a neighbor, it had sat without manifolds for many years under a porch roof, I removed the starter and with a pry bar it broke free, loosened up and had one stuck up valve, I used a brake adjusting spoon through the spark plug hole to pry against the stuck valve and it popped down, after it opened again it stuck, lever it down with the brake spoon and it seated, the engine has compression in all 4 now, as soon as I scrounge a manifold stud,some nuts and washers I will try starting it.

Interesting. Is it advisable to try to squirt MMO into the spark plug holes at the valves?
