Just wanted to come full circle on this thread and update everyone:

Spent some time with the timing today. Results as follows:

Initial 13°
MVA connected idle = 35° (car's sweet spot is 36°, and it HATES ported vacuum advance, surges and runs hot).

Car idles good, no ping at all. Temps are way down around 175-180°, but it's very cool out tonight and I didn't drive as far as other days. Oil PSI is good too.

I am still getting a slight surge at a steady 3,000 RPM, but not as much as before (but again, it's not as hot out).

I'll wait and drive it again on a hot day before I do anything else.

WOT power seems a little down, otherwise, running well. And as stated, when it's cool, oil pressure is good.
