The correct gakset for stock heads and Edelbrock Performer 5.0 lower intake is Felpro 1250. A Felpro 1262 is basically the same as the 1250 but has larger port sizes for larger head/intake ports. Both will work fine for street use. I have used both for several years on the street and never had a problem with them leaking.50bomber said:I apologize if this is a repost, but I have checked the search and there wasn't any answers to this question. So here it goes; what is the correct lower intake manifold gasket part # for stock heads and Edelbrock Performer 5.0 lower intake? Question #2 Is FelPro 1262 gasket fit to be used on the street with reasonable amount of miles before it starts leaking? Thanks for any replies.
Is the FMS-M9439B302 same as FelPro 1250? It states in the Motorsport catalog that their gaskets are made by FelPro, and this is the correct one to use with street aftermarket intakes, thanks for your repliexs
