I don't think pistons can be taken out thru the bottom on very many engines.
Pour some Winter Green on top of the pistons/around the rings, let it soak for a few days, pour in more Winter Green as it might drain away past the rings.
Turn the motor upside down, pour in more Winter Green, let it sit for a few days.
Then pound away from the bottom.
