p.s. it has been my experience that after installing headers for a dual exhaust or a big single for that matter is to put in bigger jets on the carb beacus the increased efficency of the headers creats lean condition in the combustion chamber.that may not be so in a split system in a straight 6 however i would check spark plugs and adjust carbueration accordinly after doing so.
