Hello. Has anybody got a tip on wich shorty style headder will fit with the least h***el in a 1956 fairlane with a 390? The engine is fastend with what looks like the stock y-block motor mounts, and it's tight around the engine. Maybe it's possible to raise the engine some with spacers? Would like to have a better flowing exhaust than the stock logs to complement the aftermarket intake and upgraded cam that's in there.
