Aluminum stamped valve covers

Scott,
Have you entertained the idea of a vacuum pump? I know this would require some differences in the engine build...ring package and rear main seal to be specific. But I have been running a vac pump for a few years now...what a difference in how clean the exterior engine stays. No leaks of any type! And...the real benefit...more horsepower and not real expensive either.. Once the system is purchased, maintenance on it is not much. Just a thought. Also, maybe you can "restrict" the oil leading to the rockers, this would be a good thing for the rods/mains...
