Hello again, Im looking to get some clarification before i send off the engine to the machine shop. Does the 409 need push rod guide plates? Im missing two rocker arms are those interchangeable with other SBC or BBC engines? Im missing a few pushrods so i think i should get a new set of those and im not sure on what specifics I need for the pushrods. My main caps have the taller bolts for the windage tray but I believe my oil pan has one built in, so I believe I don't need to use the tray. Any and all advice is much appreciated.
