I'd opt for the later of the two as your machinist can also check your guides, cam journals, and set lash whiles he's in there.

Thanks for the reply. I think i’ll give it a try to lap them myself. If it turns out to fail, I’ll try to find a machine shop to ship the head to.
Maybe a stupid question, but can I really rule out bad piston rings? Can this little «offset»in the valves make the compression go from 160psi to 40psi? I might be totally wrong, but I feel like there must be a bigger leak somewhere. That beeig said, I haven’t looked at the valves and seats yet.
Is it reccomended to lap all the valves while I’m at it or is this a situation where you would say: If it ain’t broke, don’t fix it?
