There is another method that has been used with success on much older engines than yours.

Make a plate to bolt on the top of the cylinder. Drill a hole and put in a grease fitting. Fill the cylinder with oil or grease, bolt on the plate, and start pumping it full of grease from a grease gun. This will provide up to 3000 PSI of hydraulic pressure. Enough to push out any piston without damage.

Basically the same as the air pressure trick but more powerful. Try the air pressure first, if that does not work try the hydraulic pressure.
