Backfire issues

I just put a new engine in my truck. I am getting a sporadic pop at idle and worse as the engine revs up. Someone said it could be the rockers out of adjustment, while others think it is the carb or spark plug wires. The pop is coming out of the exhaust. I am not sure which way to proceed. The engine ran fine when we broke it in 2 weeks ago, but started this last weekend. Anyone have any ideas?
