Norton Gasket (Eyeletted), Cylinder Head
Eyeletted cylinder head gasket for the engine top end, cataloged for 1975.
This is a cylinder head gasket, eyeletted construction, for the engine listed in our records against PN 06-5051. It sits between the cylinder and the cylinder head, sealing the combustion chamber and keeping compression where it belongs.

The catalog entry ties this one to a single year appearance, 1975, and the figure title places it squarely in the cylinder/cylinder head area of the engine top end. Beyond that our record doesn't spell out which specific model it was fitted to, so if you're matching this against an engine you're rebuilding, check the gasket against your existing part before you order.
An eyeletted gasket has reinforced eyelets around the bore openings and stud holes to help it hold up under repeated heating and cooling cycles. If you're doing a top-end rebuild, it's worth having a fresh one on hand rather than reusing an old one that's been compressed and heat-cycled already.
