MED ST3 ULTRA LIGHT ASSEMBLY EN24T
( £395.83 EXC VAT )
The combustion chamber is modified with full radius side walls and double radius valve seats, which are all cut to race tolerances. This helps to maintain equal combustion chamber volume and equal valve spring fitted lengths. The valve seats are 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 three-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 of the valve springs
The head comes fully assembled with race valves springs, steel valve caps and new single groove collets. Painted and ready to fit.

Please note, these cylinder heads are machined to order - once you have purchased this product a member of our sales team will contact you to finalise the specification and advise delivery. Delivery is usually around 10-15 days from the initial order. The price advertised includes a surcharge of £250.00 which can be credited back to the customer once a serviceable cylinder head casting has been sent back to us as an exchange unit.
For race heads we insist on using castings without valve seat inserts, so the exchange unit must be of this type. Please contact us for further information.
