I recently did a full head gasket replacement to fix it blowing white smoke out of the exhaust, which worked. Now after putting everything back together ive noticed a few small problems. I bought the truck knowing it ran but i never layed on the gas because of the bad head gasket, so not sure if the backfire was from the fix or it was from before. I only notice the backfire when i really give it gas, and its a low popping noise with the occasional loud one. I did a compression test on all the cylinders and found 4 were at 160-165 and the middle 2 were at 140-145. The middle drivers side spark plug was completely black and not sure what that's from either, as all the others are brand new clean plugs. Any help is appreciated, i can try to give more info but i only know so much.
