What material are these head gaskets made from?

These S&S Cycle head gaskets are made from copper. Copper is chosen for its ability to handle high temperatures and conform to sealing surfaces, which helps ensure a leak-free seal.

What is the bore size and thickness of these gaskets?

The bore size for these head gaskets is 3-5/8 inches, and they are .032 inches thick. This precise sizing is critical for proper engine compression and sealing in the intended Big Twin applications.

How many head gaskets are included in this pack?

This pack contains 11 head gaskets. This provides enough for a standard engine build with spares, or for multiple projects.

About this part

Product Details

These S&S Cycle head gaskets are made from copper and measure .032 inches thick with a 3-5/8 inch bore. This specific sizing and material choice is important for achieving a proper seal in the 1966-1984 Big Twin (BT) engine applications they are designed for.

Copper is a well-known material for head gaskets because it offers excellent thermal conductivity and conforms well to sealing surfaces, helping to prevent leaks under high heat and pressure. The .032 inch thickness is a precise measurement that contributes to the correct compression ratio and cylinder head sealing for these engines. This pack includes 11 gaskets, giving you spares or enough for multiple builds.
