Leading A-Series engine specialist since 1981
Flow bench designed and tested for maximum airflow on our Superflow 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 valve spring fitted lengths.
The valve seats are blended into both chamber and port to maximise airflow. This specification comes with 31mm exhaust valves in offset guides and 37mm inlets. The head comes fully assembled with race valves springs, steel valve caps and new single groove collets. Painted, fully machined and ready to fit.
Options to be confirmed;
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.
We aim to deliver within 20 working days from the initial order, however during the race season this can vary with demand. Please contact us for the most accurate lead times.
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.
