Here is a brand new factory fresh cylinder head gasket set for your Aston Martin DB4, DB5, DB6, or DBS6. The head gasket is the current improved composition type as the copper head gaskets have been discontinued. These new gaskets have the red sealing beads around all the passages and are working great here in our shop. The head gasket will accommodate bores from 3.7 to 4.2 liters. Intake manifold to head gaskets are not included as SU and Weber use different gaskets, which we have in stock.
