If you have difficulty removing a cylinder head please do not resort to using screwdrivers, chisels and hammers which will damage the joint faces & your screwdrivers. The photograph shows the hammerless method I use. I've used two old Champion 8 COM spark plugs from which I've removed the ceramic insulator and replaced it with a long 5/16” BSF bolt and large heavy duty washer and nut, these are screwed into numbers 1 and 4 spark plug holes. I have a piece 2” x 2” x 1/4” angle iron drilled to pass over the 5/16” bolts in the spark plugs. This is also drilled with two holes for my chain block to lift either the engine or engine and gearbox. I then place steel plates over the ends of the cylinder head studs and under the angle iron. Tightening of a second nut on each 5/16” bolt will draw the cylinder head up until the head is flush with the ends of the studs. If you still can't lift the head off, replace the steel plates with two bolts, of the same length, on top of the cylinder head studs.
