I think I might have found the source of my valve issue

As in labor to remove? If so, they only rebuild heads. No remove and replace.

Na, just in general. I don't have the facilities or a torque wrench to do it myself. Their website says $175. At that price, that is what I will do, comes with a 12 month unlimited mile warranty. Fully rebuilt, I'm in. Now just need to find someone to do the work for me.
