I picked up a 1954 Ford 1/2 ton pickup, from South Dakota, it has a straight 6 cylinder (Overhead), and a 3 speed on the colum. The motor was rebuilt several years ago, ( probably in the 1970's), but then it was parked, and the motor was allowed to sit without being turned over, since. So now, I have the task of trying to break it loose. The 2 front cylinders are loose, as are the two back ones. (I sprayed Diesel Fuel in those cylinders and had let them soak, and the Diesel Fuel eventually soaked in. (I also took a round wooden handle about the size of a hammer handle and went around the top of each piston and tapped the top of the handle with a hammer. Like I said, all are broke loose except for the 2 middle cylinders. Those do not wanna break loose. I have tried Diesel Fuel, Marvel Mystery Oil, Stoddard, PB Blaster, Liquid Wrench, and everything else available. I was wondering, if I were to take a cutting torch, and just very lightly warm the top of the piston, and possibly the expanding and contraction action would help loosen it up. Would this work? Or does anybody have any better ideas? If so please feel free to let me know. Using the cutting torch is my last idea, short of pulling the motor and tearing it appart. I do have another motor that does run, but this one being rebuilt, I thought I could save it. Anyway any suggestions or ideas are greatly appreciated, thank u all very much.
 
Is the head off the engine?? If so,I would get a large wooden block about the same size as the piston (shape it if needed), place it on top, and give it a good solid smack with something larger than a regular hammer.
 
You might try putting some kind of rotational force on the flywheel while tapping as well, since you have most of the pistons free. It might be hard to tell which way it needs to rotate, tho.
 
I agree with Parklane, and stay away from prying on the flywheel or twisting on the damper bolt. If you're going to use any heat, I wouldn't go hotter than a propane torch.
