Freeing stuck valves in a Ford v8 flathead [SOLVED]

I have a 1940 Ford v8 flathead with 2 stuck valves that I know of. Would Sea Foam Spray help? Or Sea Foam Motor Treatment? And how would I use it?

Hi Richard. What I’d do: If the engine runs, start by doing one Sea Foam Spray treatment (full can) into the carburetor throat. Every treatment will progressively clean and lubricate around the backs of the valves, so do as many treatments as often as you wish. Adding half a can of Sea Foam High Mileage to the oil crankcase will also help clean on the oil side of the valve mechanisms.

Here are two more resources to check out for more info.
