So I have oil leaking from the left side of my just-purchased XS650, specifically from the head gasket. It runs good, so no compression issue is evident. I saw this old thread:
http://www.xs650.com/threads/leaking-head-gasket.30135/#post-302298
The members there talk about retorquing the head bolts, which I have already been advised to try on my 1980 Honda CB650 which has a similar issue. I'm good with doing that, but the thread above is light on details, and I'm the sort who likes to have everything nailed down.
First of all, brass washers are mentioned, from Mike's XS. Is this the correct part?

According to the parts fiche on CMSNL (which is the one I use all the time for my other bikes), there are 4 part no. 90210-10004 washers used, which according to Mike's XS are the equivalent parts to the brass washers they are selling. But according to the parts fiche, there are also 4 part no. 90201-10131 washers, under the other four acorn nuts. I don't find a replacement for that part... what exactly is needed here?
Incidentally, I did find this part: https://www.mikesxs.net/yamaha-xs65...0430-06014-90210-10004-00-90201-10131-00.html
It claims to be a "Bottom end" kit in the title, but it says "top end" in the description, so I'm more than a little confused.
Mainly, I just want to know what the procedure is before I start. I assume the nuts get removed one at a time, replacement washers fitted, and then retorqued to 30 foot-pounds for the acorn nuts, and the factory 14-16 for the other head bolts/nuts. Do I have this right?
