I bought just about everything possible to solve this issue, just haven't had time to install it all. I still need to install:
-Stainless fuel lines
-Fuel Pump
-AFR gauge
-8.5 power valve (and carb rebuild kit)
The good news is that I think I found what was fighting me and I have the engine tuned really, really close. So turns out the "brand new" cardone dizzy I bought had a leaking vacuum advance can. With a non leaking vacuum advance, it runs much better. After much reading of forums, I also decided to switch to manifold vacuum for the vacuum advance.
I still have the very slightest of small stumbles but I will install the AFR gauge to help dial in the carb tuning and hopefully get it 100% solved.
I ended up using the blue pump cam and .035 nozzle for now. The pink cam is actually significantly less aggressive than the orange and the orange and red appear to be identical.
I am not exactly sure what detonation/pinging sounds/feels like but I definitely did something that my engine was NOT happy with. With the defective vacuum advance can installed, I had 2-3 instances where at WOT I would have a severe hesitation, with some smoke from the engine, and I immediately let off the gas and everything went back to normal. After looking around the engine bay it appears that it was some kind of backfire as the intake gaskets got pushed out which also is causing a very very minor leak at the engine block as well. Ill add reinstalling the intake manifold on the list of things to do. With the new vacuum can on, the engine is running great and this issue does not happen at WOT anymore.
I did a compression test and the engine seems to be in good working order. Cylinder one is actually closer to 140. I checked it a second time and got a higher number.
I think after reinstalling the intake, replacing the steel lines and fuel pump, installing the AFR gauge and fine tuning the carb, I am happy to report that this engine appears to be healthy and will be I'll be confident in saying that it's in good working condition. Oh, and the engine is pulling close to 18" of vacuum so I will try swapping out the 8.5 power valve and reclean the carb when I install the fuel lines and fuel pump.
