If it didn't do that with the original filter, do a test by putting it back on to see if the popping goes away. Sometimes you end up hearing something the engine was doing but couldn't be heard with the factory filter. Other times aftermarket filters disturb the entering air flow to a point where the carb is in a buffet condition that results with irregular fuel delivery.
In actuality the factory air filters aren't very pretty, don't look racy, but do a damn good job of smoothing and orientating the air flow into the carb's air horn. Over my many years at this I haven't found many aftermarket filter kits that worked very well. For the street it's mighty hard to beat a factory closed box with a K&N filter. A closed box so you can connect it to an outside air source that is cooler than the air found under the hood. You get almost a 1% power gain for every 10 degrees you take off the incoming air, the simplest way to do that is to access air from outside the engine room pulling it in next to the radiator behind the grill is a good place. If the factory air cleaner has an external heat riser where it pulls the air over the exhaust when the engine is cold this can be made into more improvements. If you live in a cold climate if you cool the intake by cutting off the exhaust crossover you'll get ice formation in the manifold and at the base of the carb. There is power to be found by shutting of the crossover, but along with that comes miserable cold weather running. If you take the hot air stove to the air cleaner intake and put an old choke control cable on its door so now you can open the door to admit hot air when the engine is cold to prevent ice formation with no crossover. Then close it when the engine warms up to maximize the temperature drop of the incoming mixture. Doesn't look cool but helps blow the other guys doors off.
