I don't mind having to run a valley cover, and I think my chances of finding a 337 manifold are slim, especially in my part of the world. I think I will go with the 440-2 manifold, and have Hughes deep port match it.
[quote=AndyF]I do have MW size batwings that will work with a billet valley cover with the Stealth heads.
Andy, what are your part numbers for the batwings and valley cover that suit the Stealth MW port heads on an RB block? [/quote
I used Andy's stock port batwings , fitted great . I used the Trickflow plate , has removable centre . Also recommend seeing if Superformance do the various thickness intake gaskets like their standard port ones . Helps to juggle alignment and reduce cutting intake by buying a few sets . You use a gasket each side of the batwing . As to an intake you could be surprised , ask around on the facebook Aus Mopar pages .
oh , I almost forgot . I think the 4150 Victor may have enough meat to open up . I know the standard port Super Victor , 4500 , does . . I can look later on mine if you want . I don't think the M1 will , can check that as well
