I took the camshaft off the head, found it along with the camshaft caps and where the cam sits on the head to be scarred and pitted. Is it salvageable or trashed. How can I , if at all, fix this? Or do I need to get a new head.

 

Those don't look too bad.
Have you plasti-gauged the cam saddle to journal clearances??

 

No. I can though. I was in OMG mode with the looks of the cam and the journals. I THOUGHT there would be bearings like the rod and main. But apparently I just learned me something! How bad does it have to look before it's a giant paper weight...

I haven’t heard anyone mention cam journals as a reason to scrap an OEM 22re head. If you lose the caps, however you’ve got problems.

 

The loading on the cam journals is light.
If the clearances, as shown by plasti-guage are reasonable, you should be fine.
I'm sure that there must be some specs for this clearance in the FSM, but I don't know what they are, offhand.
I would think several thousandths, at least.

 

0.01-0.05mm, maximum 0.10mm

You might need both red and green plastigage to cover that range.

 

.10mm is just less than .004 inch.
