When building a high performance engine with a solid or solid roller cam, it is necessary to meter the amount of oil going through the lifters and up to the rocker arms. Too much oil to the top will starve the main and rod bearings and cause engine failure. These oil restrictors are simple and easy-to-use parts.
With a .055"orifice, this pair of oil restrictors reduce oil flow to the top end of the engine which ensures bottom end oiling.
