BTR has sourced our very own MLS head gasket that can be used on 4.8L, 5.3L, and LS1 engines. These are possibly the best gaskets for engines up to 3.920" bore. This is a direct replacement for the LS1/LS6 GM head gaskets. This gasket has everything you know and love from the GM version: High quality, MLS construction, and it's produced by the same source as the OEM units!

3.920" bore, .051" compressed thickness
