8.3 MBR/Fontana/Arias Embossed Copper Exhaust Gasket

RBS carries a full line of MBR/Fontana/Arias 8.3 copper exhaust gaskets. These gaskets are made from soft copper and will seal the header to the head with no problem.

These fit the 8.3 MBR/Fontana/Arias with a 2.50" x 2.00" rectangle exhaust port. Ports are embossed to offer a crush when the header is tightened down to provide a superior seal.

Exhaust gaskets are set up with ten 3/8" stud holes and are sold in pairs.
