I installed the standard AC R44TS plugs. The '72 LT-1 (w/AC) is all stock, except for headers and 8mm Accel wires. There is a Holley 3310 carb that I will be replacing with the correct Holley 6239 very soon (it's on the way). I'll keep the stock jets in that as well.

I found my Holley spec sheet. These are the jets for the LT-1 Holley 6238 & 6239. It's been so long since I jetted a carb that these may be the Holley part numbers. Hope it helps. I have the other carb part numbers as well if you need them.
Primary Main Jet: 122-68
Secondary Main Jet: 122-73
Primary Main Jet: 122-68
