late model slant six head
I did see it mentioned but want to restate... take the valve cover as they are different for the newer 'peanut' heads from the 'drool tube' heads
OH! there is an air injection port right behind the #6 cylinder that will have to be blocked either by tapping a plug or fabricating or getting a block off plate. Dodge does have a part number for this... Gasket pn 4275834, Plate pn 3751249
