you might want to try hitting it with a RUBBER mallet--be sure that you take the two oil lines out of your head so u don't bend them during the head removal!!! hope this helps

We found the easiest way is to:
1. Make sure EVERYTHING is disconnected from the head.
2. Attach a heavy rope to the head or better yet, a chain to a hook installed in one end of the head. Make sure to use a heavy-duty part or threaded hole to connect to so you don't bugger up anything.
3. Pad the area around the head with old rugs or whatever so when the head pops off it doesn't mash anything if it swings sideways a little.
3. Hook the other end of the rope or chain to an engine hoist and with a little pump action it'll come right off without damage.
Hope this helps.

First, make sure ALL the bolts are out. I know from experience, heads are hard to remove if you haven't removed all the bolts, no matter how hard you pound a chisel into the gasket.
Can you turn the motor over? Air pressure from cranking the motor should create a hundreds of pounds of force to pop the head off (100 psi in one 3.5" cylinder should produce 960 pounds of force). I'd leave a couple of bolts with maybe an 1/8" of slack so the head doesn't jump too far.

What angus said, air pressure. Does the engine turn over? Can you install a starter? Maybe back off all the exhaust rockers and crank that puppy with the starter. Maybe that'll pop it off.
Good luck,

On studded engines frozen for years,
we have brazed grease fittings into spark plugs,
and stick a wire down the plug holes to find
two even pistons up and pump in the grease. Can't
beat the power of hydrowlics!!!!!!!
