Production tolerances on Twin Cam rocker covers can allow them to shift when being tightened, leading to misalignment. This not only looks bad but can compromise the sealing surface, leading to all sorts of engine problems. In engines with high lift cams having had the rocker covers relieved, misaligned covers can cause rocker interference unless extra material has been removed. For these reasons, Jims has developed alignment screws to ensure that rocker cover alignment is correct. This product offers an improvement in both form and function of Twin Cam rocker covers. The quality you expect from Jims allows for a lifetime guarantee on these made in the USA screws.
