Update: I went to the feed store today. It's about 6 miles away. Truck held 180 the whole way.
Before i turned off the truck i used my digital thermometer and the intake below the carb at the choke pocket was 300 degrees. The base of the carb itself was 164. The exhaust manifold was 700+
Went inside and bought some feed for my wife's critters and before i started it up i measure the temps again the intake had cooled to 230 but the base of the carb heated up to 170 to 210 depending on where i measure it.
Drove the truck home and sure enough it would bog when it did not on the way to the feed store. By the time i got home coolant temp was 180 but the base of the carb was still in the 170 to 200 range - it was warmest near the choke pot.
I am going to try the thick spacer first and see what happens.
I plan on taking it on the power tour this year so i will probably pull the intake and block the heat ports. I'm running an electric choke and i live in Florida so i am not too worried about it being cold natured.
Thanks for the pointers everyone - i really appreciate it.

truck weighs 4500 pounds - just cruising it on the highway.
i'd like to think it is the crappy alcohol blended fuel, non-hardened seats and no lead additives is what burned up the 906 heads.

UPDATE -
i think i have figured out the root of my problems. it appears the springs on the mechanical advance in the distributor have stretched out. last time i messed with the timing on the truck i set total advance at 36 degrees with initial being around 8 or 9.
when i went to check total advance last night it had worked itself on up to 42 degrees! i backed it up to 36 total degrees and then idled it down and initial timing is now reading 6 degrees.
does a 30 degree curve seem a bit unreasonable for a fairly stock engine?
anyone know of a good resource to get a rebuild kit for an original dual point distributor converted to pertronix? i think i need to narrow down the distributor curve a bit because it is a bit gutless off the line - we can't have that now!
Thanks MOPARTS!

For sure not enough initial & you need that amt finalized (vac gauge method is good) then shorten the slots for 36 total (WO vac hooked up) then play w the springs then hookup the vac adv (if used). Right now your total is good but the slots are too long which is making the initial too low and the curve is too slow and that's what's hurting your performance.

I had mine welded, then I attacked it with a routing bit in a dremel and a grinder to smooth the bumps out and to get the desired length. If I did it again, I'd weld the inside of the slots, so that the springs have a bit of pre-load on them. https://board.moparts.org/ubbthreads/show...part=1&vc=1
If you ever find yourself in a fair fight, your tactics suck.
