wow, talk about a stubborn head, i to have done used the handle of a hammer, it was on a lawn mower, but still. DON'T USE ANYTHING THAT WILL DAMAGE THE HEADS, make sure the tool you are using is softer then what you are prying on, learned that one the hard way and had to get new heads.

Why couldn't it be done on an OHC engine?

Because you've got a chain or belt that attaches the cam to the crank. If you remove that it wont open and close the valves and the piston may hit the valves. If you leave it hooked up it may damage the head, sprocket or belt when it comes loose.
You could pull the rocker arm ***. and the cam belt, and then do it, but that's the only way to do so with an OHC engine.

success @ separating the head from the block

The problem was gasket sealant and 14 studs.
I used air pressure through the spark plug holes, and was able to verify the head was loosened. This also partially separated the gasket from the head, and with a little perseverance, the hoist was able to pull it off.

1st time I've used the forum, and want to thank you all for the help.
