So the heat idea works.
I fired up the torch and I had my cousin working the hammer and he tried pounding it through as I worked the torch and infrared thermometer.
It started out with a solid knock at room temperature. Once it reached about 365 F the knock turned into a hollow thud. It still took a beating even when hot but at least it was moving. I was spraying pb blaster and the piston very slowly worked its way through till it was out.
When the first piston came out I grabbed it to prevent dropping it..... HOT HOT!!!!
But the last two pistons were freed and all pistons are out of the block with no damage to the walls or the pistons. One connecting rod cap got a little beat up by I'm thinking it will live?
