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.

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.

|jeffery wells||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.|

How about a cast iron flathead with studs instead of bolts, my Rambler was a challenge!
I bolted a chain to the intake studs and used the cherry picker.

|1971BB427||I've used the cranking engine (with plugs in the head!) often, but if this is an overhead cam engine it should not be done. It only works with engines that have the cam located in the block.|

when i was a wee lad, i remember my pops doing this on his ford I-6's talked to him today and asked what he used, turns out he defiled a sparkplug, tapped a hose fitting into it and hooked the air up that way, he says he still has it and he said he would give it to me, dont really need it, but it would be a nice convo piece.

|curtis73||I was able to get mine off an old Pontiac 6 by cranking it over. The valves were closed, but the pressure had equalized in the three cylinders in the down position and the rising pressure lifted it right off. I might have someone holding the head in case it decides to pop off the pins.|

|lmsport||In old Triumph/Austin manuals, they recommended loosening all the head bolts a few turns, then turning the key in order to pop the head loose with combustion pressure. I saw my Dad do this a few times.|

|DanielC||Pay close attention for any other bolts. Some engines have bolts on the ends that are not head bolts, but are there to help seal oil, or water passages. Very common on ohc engines.|

It does sound like a bolt may still be in it.
Last resort- Put the plugs back in it and spin the engine over w/the starter. Thread some head bolts back in finger tight so the head doesn't pop off.

|T-bucket23||Gasket sealer should not over power a 3' bar. Double check for bolts. Sometimes they are hidden in the corner or between valves. If you check a torque sequence chart it should identify where all the bolts should be.|
