1973 intakes had EGR and AIR emission controls. None of the aftermaket intake manifolds have provisions for these, except for Poston's S-divider which has EGR. Might not be a big deal for you.<P>You might have to plug the AIR holes on the cylinder heads along the intake manifold mating surface depending on the aftermarket intake and intake gasket you purchase.<P>Sorry, but I don't know the different gasket part numbers.<P>As for aftermarket headers for a Buick 455 that would fit a 56 chevy pickup...I don't have a clue on that one.<p>[ 06-04-2001: Message edited by: Straycat ]
