You know as well as anyone, there is fit and then there is fit. The rockers probably fit fine with stock diameter springs. They will surely make the valve go up and down. Obviously not optimized but that is part of the joy of buying bottom dollar parts. The fact that their own brand labeled rockers align so poorly on their own heads should be embarrassing for them. Product Marketing people have no soul, they sell whatever you put in front of them. It's a shame they don't do the little bit of design changes required to make everything line up like it should but they are probably too busy making and selling Ford and Chevy parts by the shipload, rather than a few containers of Mopar parts. The date codes on some of these heads is telling. They obviously haven't been flying off the shelves and requiring multiple casting runs each year to resupply.
