Dr. F--thank you for the info. As usual it is appreciated.
Will I need to run premium gas or get by with regular gasoline?

You could try the mid grade and see if it pings. Be prepared to back off some ignition timing until it doesn't ping if you try it.
other pinging alternatives include:
100LL AvGas
racing fuel
leaded fuel additives / octane boosters
use http://airnav.com/fuel/local.html to find an FBO near you. my lowest local price is $3.66 / gal

umm, wasn't that true of pretty much everything out of Detroit back then? that was the whole point of "blueprinting" engines.
