I think you are referring to the 4.6 2v heads . Brandon is talking about the SBF 185 casting . I have heard they are complete crap and the worst casting on the market . The pictures I seen on Hardcore 5.0 looked terrible but others have said stuff about the Pro Comp head and mine looked fine and flowed decent numbers . I am sure with some work , they will do fine for a budget build up .
