"Made from 7075-T651 aluminum with a tensile strength of 83,000 psi, which is double the amount of 6061-T6 aluminum and almost triple the amount of cast cam covers. This cam cover is positioned precisely to the centerline of the cam bushing and pinion bushing. In fact, this cam cover is within .0002” of where the factory intended it to be. Why hold centerline that close, or for that matter, why even care about centerline in a cam cover? We at JIMS® are concerned with the life of your motor. For this reason, we are helping you to achieve long life of your valve train components, consisting of your cam, tappets and your tappet blocks. Your cam shaft must lie on the best possible foundation. The foundation we are concerned with is the centerline of the cam shaft. If the cam shaft is tilted off in any direction much more than the running clearance at each end of cam shaft, this will affect the way the tappet rollers ride on the cam lobe. If they are not riding flat, but on one edge of the roller, it could possibly shorten the life of your valve train. The cam shaft is supported at both ends, while the inner cam bearing is a given, meaning the bearing is not going to move unless you do a lot of machining. Your cam cover must be right to the case centerline for the longest possible tappet and cam life."
