High Performance 1275 Head Gasket
Head Gasket Mini/metro 1275
Original competition copper/steel head gasket. Manufactured by Payen to their latest specifications. Essentially used on 1275cc(or any Cooper S) engines, but also for small bore engines when using 12G940 head casting and slightly oval bore holes; hence 3.7 compressed volume. Three waterway holes are larger where expansion occurs.
