My exhaust valve stem measurements are barely in spec, but not at the service limit. I was wondering if I should replace them or just run them for another season.

Exhaust valve stem spec: mm(in)
4.965-4.980(0.1955-0.1961)
Service limit: 4.96

Current specs:
Left exhaust: 4.966
Right exhaust: 4.965

should I run them or replace them?

If your valves are that wore, chances are your guides are toast too. Pull the valve out so the tip is just above the top of the guide, how bad do they wobble? Assuming the head hasn’t been touched, I would send the head in for guides, valve job, and new valves.

I have never done this before so I can’t compare it to anything, but they don’t seem to wobble that bad. They do wobble. I can’t see it wobble by looking at it but I can feel it
