The Cometic SR20DET head gasket for Nissan S13 is a multi-layer replacement specified at 86.5mm bore and 0.060" thickness without an extra oil hole. It requires less clamp load and conforms load distribution across the sealing area. The design reduces bore distortion, needs no sealants or re-torque, and is intended as a direct replacement for S13 SR20DET engines where that specification is required.
