i have been staring at this pic and can't see it either?
one thought was a shim on top of the valve spring but how to move the rockers up & out of the way??? i don't see any thing near the cam lobes. do the rocker rollers come out and thus create room above the spring to get a shim in there? or do those 4 bolts (2 silver 2 grey) allow for the rockers to come out all together?
