CLUBMAN OFFSET RACE HEAD

Flow bench designed and tested as our Clubman specification for maximum air flow on our Supaflow 110 flowbench. This head uses the very latest development in port design with high roof inlet ports and negative radius valve guide boss removal.

The combustion chamber is modified with full radius side walls and double radius valve seats which are all cut to race tolerances this helps maintain equal combustion chamber volume and equal important valve spring fitted lengths. The valve seats are then blended into both chamber and port to maximise air flow.

The main significant difference with this specification is that we offset the centre line of the exhaust valve which in turn enables us to fit a larger exhaust valve, ideal for race engines. This specification now comes with a 31.0mm exhaust and a 37.0mm inlet valve. They are race quality 21ns steel plasma nitrided with wasted stems and 3 angle valve seats.

Before our own hi-flow silicon bronze valve guides are fitted the valve spring platforms are machined to maintain equal fitted length valve springs

The head comes fully assembled with dual rate double 240LB race springs, MED steel valve caps and new single groove collets and is painted and ready to fit.
