I am in the process of doing the valve stem seals and just cleaning up the head in general from my 85 8v. The head is currently off. After pulling all of the valves out, I noticed that at least one of the valves has some extensive pitting up the shaft, and several other valves have some less worrisome pitting on them. Should I just replace the valve that looks pretty bad? or should I just get all new intake and exhaust valves?
And if I get new ones, is there a proper way to get them to seat?
Also while trying to get the first valve stem seal out, I grabbed the valve stem seal on the inside and put a little scratch into it. I'm wondering if I should get new valve guides.
