Rocker to Retainer with Pictures

I ran across that issue on a couple of engines using the 273 adjustable rockers. On one I was able to grind a real small amount off the cast iron rocker. The other, I had to use beehive springs with smaller retainers to get enough clearance. Neither engine had cam lift as high as 1/2" and neither was going to see 6 grand, so, I was not worried about a little grinding on the rocker. I've got over 75k on that one at this point with no problems.
