To control the oil in the top end of the engine, I'm using Billet Fabrication "oiler" valve covers. The covers are plumbed into the oiling system with these Earls -4 braided steel lines (left hand) to spray a light mist of oil on the valvesprings. This increases valvespring life while reducing the amount of oil in the top end of the engine. The right hand is pointing to the Y-fitting to feed both fuel rails. Notice that the MSD distributor was ordered with an electronic trigger output (small wires at top of billet housing) to give the fuel injection computer a reference of where the No. 1 cylinder is in the sequence of eight cylinders.
