Just pulled rocker covers today to check valve lash and inspect for the dreaded mayo, as I rode a few times over Christmas in 40 degree weather. Also with the oc blocked and monitoring oil temps I hoped there would be an improvement. not so. Still the front half of the cover had the yellow smoooze on both sides. Beyond that the gaps were still in spec . One thing that struck me was the difference in the amount of stud protruding above the head nuts. Both top studs were relatively flush with the top of the nuts while the bottom ones varied from an eighth to a quarter of an inch above the nut. Is this because someone did not seat the studs evenly in the block? Should I be concerned about it? It had the cam recall done by the p.o. at a dealer but I wonder if they torqued these down properly. I may at some point decide to pull the camboxes to inspect the followers at which point I could make sure the studs are evenly threaded into the block. Just curios if this is typical , thanks Dave
