That "board member" is I. After fooling around with various motors for over 35 years, I would have bet the farm I was hearing detonation from the motor. Nope. Just a common broken head stud. The similarity of the two noises (detonation/broken stud) was amazing.
Before you go mad adjusting your timing, buying av-gas, replacing your injectors, etc., pull the lower valve covers and check the head studs.
(And JW, the Blue Bomber thanks you for calling her an '82. She's really a year older. Blush. Blush.)
