AVS 650 hesitation

I have a mild 318 9:5 compression mild ported heads 260/264 duration camshaft 430/453 lift forgot the exact numbers. Got a new AVS 650 edelbrock car hauls *** and smokes them up, but at a dead stop and if I gun it it has a second of a hesitation, if I’m rolling 35mph then gun it, it will hesitate some times not all the times.

things I have checked

#1 clean gas clean fuel filters
#2 float level
#3 ignition timing has always been the same
#4 I ended changing the rods to be a lot richer and it got worse. Came with .101 jets with 70x37 I installed 68x57
#5 now I have 73x47 rods and it seems better but the hesitation is still there

I might try some thicker rods I can’t find the edelbrock chart for the 1905 carb online.

also I have the stock fuel pump, and the stock 273 commando air cleaner but I doubt it these might be issues.
