frozen engine

I have a 1956 Executive with a stuck engine. Car was driven into storage many years ago and left. Had oil in engine & anti-freeze. I tried different penetrants in the cylinders with no luck. I can move the ring gear slightly- maybe 1/8-1/4" max, but no movement on pistons. I now have heads removed and have been soaking piston tops with PB blaster and hitting them with hammer on wooden block. Article on you tube claims wood will not transfer jolt to the pistons- it says to use a metal pipe. I have been doing that but no luck. Don't want to hit too hard in case of breaking a piston. Inside of engine [cylinder walls] look to be in great condition, but no movement in pistons. Anyone have any suggestions that I may try? Thanks.
