Mini competition headgasket for 1275 or 1100cc with a 1275 head
C-AHT188- HEAD GASKET COMPETITION 1300 AND 8 PORT
Original competition copper/steel head gasket. Manufactured by Payne 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.
