Oh Boy . . . that totally sucks to hear about Gary. Hell, just bought some of his lined valve guides a couple months ago. He had such enthusiasm for our beloved Flatheads and did his best to pass on the knowledge/experience he'd gained over the decades.
We didn't always agree on how best to do things, but that was perfectly fine - I respected his opinion and he respected mine (it is what civil folks do!). My heart goes out to his family - Godspeed Gary, you will be missed!
