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.
Available from stock in 0.030" and 0.040" thickness - other options in 0.004" increments available by special order and cost will vary
