Does anyone have information on where to obtain a Top End Gasket Kit w/seals for a 1977 CB 550K ?

I just opened my top end set (77 CB550K) after pulling apart the top end of my engine down to the cylinder head in order to fix an annoying oil leak.  Sure enough, the set did not include the rocker cover gasket, and did not include the breather cover gasket, either.  Unfortunately for me, the rocker cover gasket is the one that was leaking.

It did have the hockey pucks, though.

I rebuilt my top end last year using an Athena kit.  It stopped oil from weeping from the top end for a few weeks but the leak came back and in the spring it was bad enough that I had to do it again.

I rebuilt the top end again about a month ago.  This time I used Honda parts.  I replaced the oil gallery O-rings, the base gasket, the O-rings that go around the cylinders at the base, and the head gasket.  Total cost wasn't too bad... about $80 if I remember correctly.

I have put about 1000km (625 miles) on it so far and no sign of leaking.

If you want to take a look:

There are a few other O-rings and gaskets that you might want to change while you've got it apart, but I recommend you use OEM for: the head gasket, the oil gallery O-rings, and the base gasket.

Sorry, I neglected to mention that this was the OEM top end gasket set I purchased from Western Hills Honda.  Part number: 16110-374-S01 "Gasket Set A".  $71.95 + $10.00 S&H.
