I was just wondering about it because I read somewhere that they were needed. I am running Comp Cams HE 268 kit. Any suggestions on which heads to buy? I am looking at Edelbrock 60775 or 60779 . It is a 418 stroker.
Ran eddy heads with mopar HD non adjustable rockers with a Hughes 3037 cam...231/237 @.050 with .515/535 lift........drove on street....ran it down the track...
