Are the lifters stuck or are the valves stuck? If the lifters are stuck, you can use a wooden dowel to tap on them after applying PB Blaster or another penetrating oil and letting it soak into the gaps between the lifters and their bores. More likely the valves are stuck open. If you are unable to free them up after multiple applications of penetrating oil and allowing the engine to run while pouring some Marvel Mystery Oil down through the carburetor, you will have to attack the problem directly. Cleaning the sludge out of the lifter valley is relatively easy: put on a pair of disposable gloves, scoop out as much of the sludge as you can with your hands, wipe any leftover sludge out with paper towels, and clean off any remaining surface sludge with kerosene and paper towels.

Are you absolutely sure the valves are stuck? It's hard to see how it would run at all with 3 valves stuck open. Especially if one or more is an intake valve.

I have 3 open valves and removed the intake manifold to check what was going on... the lifters are stuck and I put 50/50 acetone/atf on to see if it helps. There is quite a bit of sludge in the galley. Any hints on cleaning or is it not worth it until the valve problem is solved. The engine starts and runs fairly well...
