rocker swap question

[The1SammyD]

So I know you can put in the 5.0 rocker with changing the stud, but every one I see is and aftermarket set. I have a set of 5.0 factory ones. Would it be ok to put them in or would it be catastrophic. Let me know what you think. thank you

5.0 rocker arms tend to wear the valve tips due to improper geometry. The distance from the fulcrum to the tip is just a bit too long.

so it would need the aftermarket rollers
