Cometic Race Head Gasket
This is a special Cometic MLS gasket made exclusively for mamba motorsport for 73.5mm offset bored A series engines. It has 74mm bore through the gasket to allow the necessary 0.010" clearance around the bore to avoid any gasket overlap into the bore when fitted. Avoids detonation due to gasket hotspots Allows piston-in-head high compression engines Can be used for 74mm bore applications where the piston doesn't protrude the bore. Please select steel gasket postage on checkout Available from stock in 0.030" and 0.040" thickness - other options in 0.004" increments available by special order and cost will vary
