1964 Plymouth Valiant with Gen 3 Hemi

Making a few changes for this year to the engine. Taking the dual quads off and replacing with Ritter intake and quick fuel carb. Out with the ported early heads and replacing with ported MMX 6.1 heads. Changing cam also to a custom ground cam from FRP (done by TSP). Hoping to pick up a few horses. Let’s hope I pick up some.
hi did MMX give you before and after flow numbers on the 6.1 heads?
