Spark plugs for a SBC Chevy

Does anyone know of a spark plug which fits behind headers on a SBC 350. I tried ACDELCO R45TS and there is no room between the plug and the header pipes. I guess I need a shorter plug? Does anyone have any suggestions? I did notice Accel make them but I would like to get a brand such as AC Delco, or at the very least something my local auto parts store would carry on hand. Thank You for your help. Much appreciated.
Never had that problem. Are they tight fit shorty headers?

Maybe the headers are for angle plug heads and the heads are straight plug or vice versa? :confused:
