LIFTER VALLEY SCREEN KITS
This kit is designed to minimize damage caused by valve train and other breakage in the
engine by keeping debris away from the engine's rotating assembly and oil pump pickup.
Special pre-formed screens are secured with high strength epoxy over the oil drainback
holes to catch metal fragments. Allen socket plugs are included for installation in the galley
to direct the oil returning from the cylinder heads away from the spinning crankshaft,
thereby reducing windage loss and aiding oil control.

OIL RESTRICTOR KITS
Race engines equipped with roller rocker arms and mechanical roller lifters should have the flow of oil to the
lifters restricted. Our Oil Restrictor Kits force more oil to the engine bearings where it is needed, and also
cut horsepower losses caused by oil windage. Engine Pro offers two styles of restrictor kits. Part #29-4004
consists of a pair of precisely drilled aluminum restrictors which replace the rear block galley plugs.
Part #29-4005 consists of precisely drilled steel plugs which are screwed into threaded oil passages.
