Should I grind the steel rockers?

Which rocker arms do you have, the HP or stock run of the mill rockers? They made 340 stamped steel rockers to clear the valve springs.

Stock stamped steel rockers that came on the 318 I believe.

If all I need tp do is grind a bit where it's rubbing with my rotary tool, then that will save me some ca$h.
