273 Rocker Arm to Shaft Clearance

Remember too, these rockers were skewed all over the map as far as being consistent with ratio. Gary at RAU will fix all that in one shot when he bushes them. He will correct for proper geometry and even change them to 1.6 if you want. There's just no down side. Course there's the cost. I guess it all depends on how far you're going with the build. Plenty of builds have run them as is with no problems at all.
