Hey guys, thanks for the great responses. I've posted a few pictures, the worn lobe is position #1. (The rocker arm contact area looked good)

I'll ask my local machine shop about the spray welding camshaft repair. The other lobes look pretty good, I still need to measure them.

As for the head, today I removed rockers and springs, over the next few days I'll be spraying the manifold studs with penetrant. Gasket surface is flat as plate glass, as is the block... pretty happy about that.

I'll be replacing 2 bad pistons, all rings, seals, etc.

Block is submerged in electrolysis tub to remove as much rust as possible. Machine shop will measure the bores but I'll most likely ream the lip and do the 45 degree crosshatch myself.

I'll update this issue on my rebuild thread after the machine shop weighs in.
