Has anyone changed valve stem seals and springs without taking the head off ? I've read about guys doing it on small block chevys using either compressed air or soft rope inserted in the plug hole and the piston carefully raised to support the valve. Not sure how you would compress the spring tho, some sort of lever arrangement maybe ?

Believe me, no matter if you figure it all out, it will be a lot easier to pull the head and then you can be assured it is done right. Save you a bunch of busted knuckles too!

Once you un-can a can of worms, the only way to re-can them is with a bigger can. -
And I was going to add that IF there is that much WEAR to the point the seals are leaking, then you've probably got lots of junk/corrosion or such on the valve shafts....as well as posssibly burned oil in the valve face/seat junction. So...will be a good time to also LAP the valves/seats while you've got it apart to help freshen up the top end sealing properties. Perhaps even decarbonize the top of the pistons and the combustion chamber as well.

Springs
Buy some new springs and seals. Take them, the head, and the camshafts to a reputable machine shop.
The shop can clean (media blast) the head and valves. They will reface the seats and valves. They will also adjust all lashes so you won't have to. You may or may not end up needing some new valves.
It is worth it to have this done.
My 2 cents.

I have done it on a small block Chevy, very easy, but yes, you compress the spring with a lever. The fulcrum point is the rocker arm stud. As there isn't one on an XS, that's not going to fly. If I thought about it long enough, I could probably come up with a way to do it on the XS, but there doesn't seem to be a real point to doing it that way. May as well pull the head and do the seats, seals, and valve clearances all at the same time without worry of dropping a valve into the cylinder or buggering something else up. Take the time to do the job right, you will thank yourself later. Have a nice day and ride safe
