At 60k, i would be expecting a lot of things to be beyond service limit now. Even if everything looks ok to the eye, everything needs to be measured, including the bores, to see if they are close to or beyond spec. A rebore is most likely at that mileage. Are your Honda pistons / rings standard size or oversize?. I'm assuming if the head gasket has been installed upside down, someone has been in there before.And don't forget to fit new primary chain when you rebuild the bottom end and cam chain, totally false economy not to. And make sure your local engineering shop know about early Honda engines, the tolerances are very, very tight on these old girls.
See I was worried about that too, but in my case the large nut wasn't in any way tight. After I unbent the retaining washer thing, I could unscrew it without needing to even use the clutch socket thing I bought! I feel like it's one of those that you need to 'shock' loose if needs be, with an impact driver.
