Bill: I'm not sure what you are inferring here. My car runs crappy with the TR55s, and runs good with the ACs. The problem lies in my set of TR55s. Hands down.
Not so much detonation, but the ignition was firing off when the intake valve was still open. The TR55s were only used for about 2 minutes of the engine running. I used the ACs to fix the problem since I realized the problem didn't lie in the plugs/wires. It very well could be I f*** 'em up. I just dropped the rest of my money on transmission fluid, so I am just going to keep the oldies in there for a little bit before I get some more money.
I want everyone who is reading this thread, who has read all this, and can contribute their opinion, on whether or not I should try the TR55s again, or if I should go with the AC-Delcos.. and if I do go with the ACs.. if I should get the stock heat range, or one colder.

And forget heatranges. There is NO BENEFIT to you or your car to run colder plugs. No harm in one range colder, but NO BENEFIT.

I think Bill doesn't like Accel..
I found my gapper this morning, checked AC'*, .060", TR55s, .060" also.
My coils are FINE, Bill. They work great. There is NOTHING WRONG WITH MY IGNITION!!! Alright? Alright. I'm going to go under the assumption now, that the previous problems with my car ruined the TR55s, thus that'* why they don't work so hot. Watch, this weekend, when I get like $2, I am going to NAPA, and I will pick up 6, TR55s. I will gap them at .060" and either they run like ****.. or they will run real good.
I'm not sure how a 'faulty coil[*]' could make one set of plugs work, yet not the other.

Justin, I'm not picking on you, but what kind of quality do you think you get from 3 coils for $30? How is heat affecting them, or how do they keep up at various rpms?
Ultimately, you get what you pay for. In addition, the TR55'* should be gapped at .055", and that may be a benefit for you, as the Accel coils won't have to work so hard to jump the bigger gap.
Honestly, I've only seen 3 other sets of Yellow Accel coils on this forum before yours, and all 3 failed early, or never performed up to par.

Get the R45LTS6 and leave it at that....
And the backfiring through the intake is not a plug related problem at all... Never was and never will be....
For whatever reason the ECM is screwing up timming.... This should never happen... If you are getting or were getting backfires through the intake that the ECM was injecting fuel and a split second later spark, before the valve could close...
Stick with the R45LTS6...

It wasn't the timing.. it was because the rockers weren't torqued to specs. That problem is long gone now.
Bill: I bought them used on eBay. Nobody else was bidding on them, and I got them for the starting price of $30. The seller said they were only a few thousand miles old, whether or not that is true or not, I don't know, but the boxes looked like they were from the 80s. So, I don't know. I would have preferred the MSD units, but I couldn't pass this deal up.
I noticed a major performance improvment everytime I switch from my [junky.. but still functional] Magnavox setup to the Delco + Accel coils. They seem to work fine for me.
As far as heat goes, the car performs great from initial early morning startup, to late night cruising. I have about 300 miles on them, and they work just as well as they did when I first got them.
Bill, here are my thoughs. Both sets of plugs are gapped the same. Wires are the same, the only difference is one set of plugs are old, and from ac, and one set is brand new, and from ngk. the ac works great, ngk works. So, it beats me. I'll talk to my mechanic friend, and see what she says. She'* pretty old school, none of this electronic whatnot, so i'll see what she has to say [owns '67 'stang.. all original too]
