273 Rocker on 340

They hit the springs too. IIRC they wouldn't even get to the point where the shaft would bolt to the head.
So, I pulled one of the rocker assemblies off last night. I was worried after comments on clearance issues. Last year I replaced my original 340 arms with Eclin rockers so I don't have an original at this point to compare but all looks good to me. Looks like there is a clearance notch cast into them as well.
