If anyone needs those crush washer things that go into the heads before the manifokds, I bought 50 or 100 of them.    Never got around to bagging them in sets of 4 and posting them on here.  I can find what I paid for them/100 and that's all I ask.  I think maybe a buck or so a piece was what it came out to.

The asbestos filled copper foil rings? (crush washers)
Retired, on the downhill slide. . . . . . . . still feels like going uphill!

Yeah-  What I ordered were those crush-rings that go into the exhaust ports and you tighten the manifolds onto.  Not sure the technical name Yamaha uses.  I measured the OD and ID of the available space and after some hunting, found a source that would work.  I'll see if i can dig them out of the shed this week and post a picture.

The part number my friend used was 31541. It is round like an o-ring and has material inside like the exhaust gasket at the port. He had to cut it and remove a little bit at a time while recurving it so the fit was tight. Just some info for those that may need it. He says it is nice and quiet now.
