I was looking into getting Edelbrock valve springs to match my Edlelbrock Performer RPM cam for my 383. The book gives a part # for Rotator and Non Rotator, does anyone know the difference or which ones to go with? I'm using stock 383 heads. Thanks
Has anyone used hooker headers #5215? Was wondering how well they fit? I can get a set of them for around $465. Or are the TTI's the better route? Any information would be appreciated. Thanks.
