Holley/Demon Carb stumble

You are not helping me with my confidence to learn to tune this carb!:BangHead::D

NO it is still the original BG/DEMON metering blocks

So i called NGK and was amazed that the recording said i had 10 sec wait.........And that was all i waited.
After taking with him a bit he gave me three spark plugs that he recommended. A platinum and double laser platinum plug and a race plug.
I haven't priced them yet but the RACING plug is no resistor. What is your thoughts about no resistor plugs!?..?!

Going to scare myself on price now.
I was paying $399 a piece for the auto light 3934 s and the NGK 4554 for $249 at Baxter's and most places.
Like I was just saying I called NGK also and decide to go one heat range lower and I had to make one store price match another to get them for $249. I like getting a set for under twenty bucks...
