Holley/Demon Carb stumble

Ok so i decide to put my 600 holley back on.
just to make sure it was a carb problem and not a coil going bad or some ign problem.
no popping and banging ran thru all three gears with a 02 reading in the mid 12's

So back home and installed 29 high speed bleeds (originals 33) and swapped back on the ProForm/Demon carb.
Darkness came upon me before i could test it. Sooo hope to get home on time tomorrow. So i can do a test stomp and load it on my trailer. So i can go racing on Saturday.
