Maybe. But I don't see what the hole in the baffle on the underside of the valve cover has to do with AFM or not. As I understand it, the hole was originally located directly (or close enough) above one of the rockers and the pressurized oil shooting from the push rod end at higher RPM (higher oil pressure) would splash into the hole. This whole area has nothing to do with AFM. I could be mistaken, but, as I said, this is how I understand it.
