Help needed separating engine section

HELP!!!
I'm having difficulties disassembling the engine of my 1980 Honda cb750.
I've beaten it with a 2 Lb. dead blow hammer for hours. I have checked and re-checked that there are no other fasteners still in place. I tried stuffing a couple cylinders with rope and try to bring those cylinders to top dead position. I'm too old to muscle things off any more.

When I did my head on my 750 f. It finally came apart when I tapped a screwdriver between the separate sides of the head and cylinder and pried it up that way . Ruined the head gasket but it got the head off.

I would suggest using a wide plastic body panel tool instead of a screwdriver. If it is really stubborn, a screwdriver will bend aluminum.
