is it a backfire or a misfire? I say check timing, touch your injectors and make sure they are ticking, check your spark plug wires and distributor.

 

Have you tried a leakdown test? It could be a bad valve.

 

If I'm correct backfire means fuel is not being ignited in the engine and gets expelled into the header->downpipe->exhaust pipe where it is ignited by the hot header/pipe.
check plugs, plug wires and timing
gaps could be wrong on your plugs
Good Luck
