Me again

If you have confirmed stuck valves and if you have the valve cover off so you can see the valve springs, I would probably take some spray oil and lube up the valve stems and see if I could work them loose maybe with a pair of pliers when the valve is off the seat.

Maybe you can loosen them up by running the starter and work on the most stuck valve stems, but oil all of them.

I don't use WD-40 for oil because it sets up and leaves a film and can seize a tight fit.

Once you get the motor warmed up and run it a little I would expect everything to loosen up and this not be a continuing issue.

When you tap on valves go gentle don't bend a stem and if you are removing valve springs watch those keepers you don't want any small parts going down in the engine or getting lost.

I learned to never hit anything with a hammer, never use an easy-out, and always put all parts back exactly where you got them. I also learned when you take things apart to take pictures, put hardware in sandwich bags and label where it came from.

I learned all this the hard way.
