Currently I have the head & block raised by about an inch and have it supported by a block of wood on the carb inlet connection things. I was hoping that overnight gravity might do its bit but no joy so far. Obviously I am tempering my rubber mallet strikes as I do not want to damage any fins. Squirting WD40 onto the visible head gasket but no movement as yet.

Presently having a long think before I do anymore to persuade the parting.
My guess is that someone has used an adhesive when fitting the head gasket.

Update cylinder head seperated using a plastic wedge as used by double glazing fitters - no damage caused !
