The mopar logo means nothing, they’ll let anyone use it for a fee. And that assumes that Proform isn’t just violating the copyright, which is also possible.
The stock adjustable iron rockers aren’t perfect and usually benefit from a rebuild. Especially on a street engine with a hydraulic cam they can benefit from being bushed with bronze bushings. Swapping out the adjusters for something with a nut to lock them down is also beneficial. Crane also makes ductile iron rockers.
That’s not a super crazy cam though, and with hydraulic lifters you might do just fine with the HD stamped non-adjustable rockers as long as the valve springs are spec’d correctly and the push rods are the right length (which has to be checked for all of them).
