How many hours have you got on the engine since you installed it? If it sat that long with no oil, the lifters might be sticking a little. Try running a can of SEA FOAM through it. You can get it at about any auto parts store and if the lifters are causeing the noise it will free them up. just run it for a few 100 miles and change the oil again. as for the running rough, after putting in a new engine, the computer will freak out for a week or so before it settles in. My 351 ran like shit until the computer caught up but now it screams!!!! The plugs should be fine, just check and make sure the gap is right....
Good luck
