Hi Charlie,
I couldn't get scheduled with the guy you said to go to,since he's super busy and could not promise a date to complete so I called around to the couple dirt track guys I new and they pointed me to "Henry in Dade city", He busy and a bit slow but does get the job done. the head came out pretty good with 1.44 and 1.70 valves new guides and springs. the height on all the valves are dead on and as soon as the block comes back I'll check if it is shrouded more than I'd like. then fix it. I have a week wait " maybe" and it'll be done.
