More update:
Spent the better part of today working on the GL. Did valve adjustments then the engine went back in, intake, belt, hoses and wires, etc. all hooked up, fluids, charged batt.... and....
She fired right up! I cranked her a bit, then let her sit a minute, then cranked her again and vrooom!
Shut it down pretty quick because the valve covers were hemorrhaging oil, I didn’t tighten them enough to get a good seal while the motor warmed up. I snugged up the bolts, let it warm up, and will re-torque the heads and install my new valve cover gaskets in the morning. Unfortunately I have to work tomorrow, but hope I can get done in time to go through the brakes and make her roadworthy sometime next week.
Thanks again to all the folks who have asked and answered questions here, it has been much easier to get this far along with all the advice that is just here for the taking.
