I just purchased these scorpion rocker arms with an advertised 500 miles on them. Is this wear normal or anything i should be concerned about?

I dont know how bad the wear is but it doesnt look like wear... it looks almost like a clearance issue. Can someone else chime in?

 

I assume its the scorpion 1.7 rockers, its tough when you have a normal size retainer, if you went with a beehive spring, you should have all the clearance in the world so it wont rub

 

its the scorpion 1.6 and i bought them used with 500 miles...dunno what springs were being run with them...i've got a set of k-800 springs on their way here that i plan on using with them

 

Yup, they were hitting the retainers. Chances are youll be fine, he was probably running a spring too large for the rockers. They are fine other wise, I wouldnt worry about it.

 

I would not consider them FINE! Wear in this area can cause stress risers that can lead to arm failure. At the least you need to hone these smooth with a fine grit stone or dremel tool. This needs to be done in a direction opposite the wear pattern. In other words the sanding marks need to be perpendicular to the wear. Also take the absolute minimum amount of material off as possible.
This is usually cause by push rods that are to short. You need to make sure that when your valves are fully closed that there is no contact in this area, along with all the other valve train geometery considerations.
