Lifter Valley Vents & Magnets & Screen Kits
STEF’S anodized aluminum Lifter Valley Vents for SB Chevys offer positive crankcase ventilation to the upper engine, eliminate lifter valley oil drain-through to the crankshaft, resultant increases in windage. An additional benefit is they keep debris from falling into the camshaft/lifter area or worse, between the connecting rods. Unlike pipe plug or screen kits which only do part of the job, STEF’S lifter valley vents provide all the functions listed.Once the OEM vent holes are tapped to 1/4″ N.P.T. all eight 21/2″ long valley vents install easily via the 9/16″ hex head machined at their top.
