Re: Valve covers for BB with power brakes
According to Jerry M's book on the 69 Z and SS396 cars, page 175, "all 396-427 Camaro engines received chrome valve covers. These covers received drippers located on the inside for better rocker-arm lubrication".
The book goes on to describe and show the "notch" (it is really more of a thumb size protrusion) on the driver side cover (that the repros with drippers do not have), and the positioning of the wire stand in front of the rear bolt hole to address clearance issues with the wiper motor in the F and X body cars.
I guess a lot of guys run without drippers, but to have them is correct and in my engineer's brain, kind of important.
