Sounds like they have just seized to the gasket. Can you not get a sharp screwdriver betwwen the block and the head to try to prise them apart? There must be some thickness of gasket you can dig into.

failing that, a sharp crack with a 2lb ball pain hammer should do it. i know it hurts, just don't look when you hit it!! choose somewhere close to the gasket line where there is some substance to the casting, if you bruise the casting it can always be stoned off, no problem.

someone has also suggested that i replace the bolts and spark plugs and crank the engine with the starter what do you guys think?

i done it 2 stroke motorcycles but not on anything as big as a V8, but i don't see any harm in it. try it.

the reference to the motorcycle only worked when i actually started the engine, the head was sealed down with silicon, clearly grippy stuff as i had to rev the engine to break the seal, it did go with a crack but nothing was damaged. when you put your bolts back in do up finger tight then loosen them two full turns, that should do the trick.

they are off at last cranked the engine and pop some idiot used joining compound anyway they are at the engineers getting skimmed ready for the new composit gaskets
