Any holley experts in the group

Here's what I have sbc 350 stock it's a Holley 670cfm jets are size 68 and squirt nozzle is a .35 not a double pumper

My issue slight popping in exhaust while accelerating more like a pff pff pff. It's very random sometimes at accelerating and sometimes at cruising speeds.Its definitely not a timing issue any advise or tips would help. About to check what power valve is in it

Dont think it's a burnt valve heads had a valve job 3 months ago

I think I would be looking at exhaust leak or ignition misfire first.
