Thanks for sharing the benefit of your experience with valves, Guys. 'Just needed confirmation. I was afraid I'd end up taking these new ones to a machine shop to have them re-faced. My luck with local shops has not been all that satisfying, so I cringe every time I am forced to avail myself of their services = $$$$$$$$$$$$$$$$.
'Looks like once again I have no choice. I wish I had bought a valve facing/stem grinding machine years ago for a couple hundred bucks. Counting up the number of times I have had to pay for this service over the years, the machine would have paid for itself!
