If you only remove 4 head bolts and the small 6mm bolt you will have a hard time getting the head off. There are 6 large head bolts.

Re: 78 GL1000 Removing Heads
If you’ve ever been turning the right cam backwards with the timing at T1 and had the valve spring suddenly move the cam, there is a significant clunk of the valve hitting the piston. Is it enough to bend the valve? It probably doesn’t take much. I don’t know, but I have also had them pop when you remove the belt, then removed the head and it leaves a mark on the piston and valve face. This was on my hybrid motor, so maybe it’s not as bad on a stock motor. I think it’s still a good practice and a good opportunity to check valve clearances as well. More work? Twenty minutes?
I have done it both ways, and as Robin said, it is much easier to turn.
Rotating the pistons down in the jugs isn’t necessary either. I still do it.

Whatever I suggest here should be given ample time for a moderator to delicately correct. I apologize in advance.

Re: 78 GL1000 Removing Heads
Okay. Next I want to replace the seals on the valve stems. What's the easiest way to remove the pulley so I can get the tappets out of the way?

Re: 78 GL1000 Removing Heads
No need to pull the pulley from the cams. The tappets and the cam holders should unbolt as one piece, then pull the cam/pulley assembly out next. That should just leave the head with the valve assemblies, at which point use your valve spring compressor tool of choice (although the big c-clamp version works best).
