Triumph 500 intake manifold to head gaskets

These gaskets will fit the manifold to the head on Triumph 350 and 500 models like TR5 and T100. Earlier models used a 1" bore (25.4mm) with 1/4" studs, part number 70-2967. Later heads used a 1" bore (25.4mm) with 5/16" studs, part number 70-6772.

Pre unit alloy 500 heads also use part number 70-2967.

Manifold gaskets should be matched to the size of the cylinder head port and the manifold bore. Please measure your stud size if unsure.
