AF Mammoth Head The New AF Mammoth Head is a direct replacement for the standard sized cylinder heads but has a significantly larger heat sink. The improved cooling results in a lower running temperature. This has offered an increased safety margin to help engines better resist seizure in adverse conditions. It has been noticed that on servicing engines fitted with these heads that top ends are cleaner and in better condition than their counterparts. The main design features of the New AF Mammoth Head in comparison to a standard head are: 1. Significant increase in the surface area for heat transfer. More and larger fins with fins on the underside of the head as well. 2. Holes between the fins around the circumference of the head to improve air flow. 3. Approx. 67% increase in the Mass (880g to 1470g) over a standard 200 head. Making the head more thermally stable. 4. Temperature sensor mounting point cast in to the head, to suit SIP / KOSO type sensors. 5. Cut away section to allow a standard clubman to fit with the Bigger head. 6. Combustion chamber designs optimized to 7000rpm with compression ratios of 10:1 with a 1.2mm squish clearance. in comparison to the standard head these have a typical 20�C to 40�C drop in running temperature, and an improved resistance to sudden changes of temperature...
