Stef's stainless steel thread in Oil Restrictors with inverted hex are a necessity for late Bowtie blocks, Rocket Olds, Darts, Merlins, and BBC because they install flush with the back of the block. These restrictors reduce the lifter / rocket arm oil supply to a 060" diameter hole and cuts oil volume by more than 70%, diverting it to where it is needed most - the main and rod bearings. These restrictors are intended for use with rollerized rocker arm assemblies and solid, roller or mushroom lifter combos. Never use with hydraulic type lifters.
