Actually two questions: I have just pulled the rear head on my VT1000CS Sabre to clean it's filthy exhaust valve, (successfully too,) and now I am told to pull the front cylinder head cover as well in order to observe it's cam marking so as to set properly the back cam shaft. OK, but won't that affect the head gasket on the front cylinder, which cylinder I was going to leave alone? Does simply loosening the head cover nuts and bolts mean that you now have to pull the head as well and shell out another $25.00 for an extra head gasket? Maybe I just aught to resign myself to doing both heads. Also, these Honda head gaskets don't require any mounting sealants, do they? Thanks in advance for any answers.

Both cam sprockets have timing marks on them and you don't have to pull
the valve(head) cover IF you are 100% sure the other cam has not moved
at all while you were working on it.

If it moved at all, you should pull the valve cover, look to the inside and
you'll see the timing mark. Align it to the valve cover sealing surface
of the head (should be 90* horizonal).
Install the sprocket on the other head with the IN stamp to the inside
and align it's mark as well.

No, pulling the valve cover does not mean you have to buy a new head gasket.
As long as you don't disturb the head gasket, you don't need to replace it.
It would be a good idea, while you have the valve cover off,
to check the head bolt torque on them though...

No, do NOT pull a sealant on the head gasket. Head gaskets and
their mating surfaces should be bone dry.
The only place you need to use a sealant is in the valve cover itself.
When you replace the valve cover gaskets, you need to put a tiny bit
of sealant in the gasket groove around the valve cover.
Then put your gasket in and turn it over. Put in on a smooth flat
surface and put a small weight (couple of lbs.) of some sort on it.
Let it sit for about 15 minutes for the sealant to bond to where it will
hold the gasket in the grove... then install the valve cover.
Don't put sealant on the mating surface between the head and valve cover
either... Tighten the valve cover bolts to specified torque.
