There was two versions of the early 4 bolt valve covers, those for non adjutable rocker arms with the stamp steel rocker arms and the other type was for the stock Mopar adjustable ductile iron rocker arms scope They are not interchangable shruggy You can run the adjustable covers on the non adjustable rocker arm heads but not the other way around shruggy
