1st time I removed mine (not same as yours) it was bound up on studs as someone before me had used poly grips to wind them out & the shafts were scored causing them to bind in holes. :151

Can you turn the engine over with the plugs in.

If Millards trick don't work have you access to a heat gun the type used for stripping paint, if so lightly warm the head and barrel area and try Millards trick again.

I am with Millard and WW on this one ~ if the cranking downes not free it.. try tapping GENTLY with rubber hammer ~ and again as WW suggestions ~

Levers as a very very last resort and used with great care.

The fins don't like being jimmied ~ ( or any other of the nordics types.. :158 :158 :155 )

Sand blasting or bead blasting, just depends what part of the world you are in as to who we might recommend, no good giving you a firm in the USA if you live in Oz

best way is to strip frame right down and sand blast it clean.

or there is this method
