Specifically developed for the late MPI engined Mini. The casting used is the correct type with the holes for the alternator mounting.
Nominal chamber volume is 21cc.
The 29.4mm exhaust valve is retained, while the inlet valve size is increased to the larger 35.6mm valve, with guide boss removal & port work on both the inlet & exhaust which vastly improves flow.
The inlet features a 3 angle seat & specially modified valve with a 30 degree back-cut for better flow. While the exhaust is single angle for maximum reliability & longlivety.
