Payen stamped AF470, Standard composite reinforced gasket used on all large bore engines by Rover is an exceptionally good gasket. Asbestos free with special black sealing ring for the oil feed. Compressed volume is 4cc. This MINI head gasket has in some cases been proven over time to be superior to other version.
The original number stamped on this gasket is LVL100380.
For performance engines and 8 port alloy heads where you should not have the rocker feed sealing ring which can cause problems, use the original TAM1521 with 3.3cc compressed volume or GEG300 with 3.4cc compressed volume or composite type C-AHT189.
