Whats all the shiny, sparkly stuff in the pics?
I think the shiny sparkly stuff is just the reflection of the camera flash on the oil surfaces.......and maybe dust in the air?
I am with JOG and agree that at this point you need to do a little more work to take it apart and get things cleaned up before you decide what to do. Remove the cam and take some find sandpaper and clean off any aluminum that has transferred onto the cam journals. We used to do this frequently on lawn mower engines that had the aluminum transfer material onto the steel cranks. Then clean the head and head cover and see if the bearing surfaces are boogered. I believe there are wear limits listed in the Clymer manual - and if you assemble the cam and head covers and use some plastic gauge to measure the clearances - you can determine if you can just put some good lube on and put it back together and run it. The bearing surfaces on the bottom side are probably worn the most - as that is where the pressure from the cam chain and from the valve springs is supported. You need to take the cam out before you can see what those look like.
The only way that I think the head can be salvaged if the cam journals are toast.....is to take the head and head cover to a machine shop. They could machine a bit off the head cover, then bolt the head cover back on and resize the cam journals........at that point you might as well just buy a used head somewhere as I doubt this would come cheap.
