Mini Mania is the exclusive direct importer of genuine Longman cylinder heads. As such we are also able to have heads modified to our specification, and we are directly involved in the ongoing development of the SCCA GT5 spec. head. All Longman heads are fully ported and polished and come assembled with Longman's exclusive valves, guides, springs and retainers.
Competition Cylinder Heads
A selected range of modified cylinder heads are available to suit a wide variety of applications. All port and chamber modifications are carried out by experts to current state of the art specifications. Therefore, actual specifications may alter slightly as gas flow and port velocity efficiency improvements are developed. Where large bore heads are used on small bore engines (i.e. 12G940 casting on 948/1098cc block), it is necessary to check full lift of exhaust valve, and pocket the block as necessary. All heads have EN214N steel valves, hidural valve guides and hi-grade valve springs. REMEMBER: Highly polished ports reduce atomization and DO NOT increase flow.Read Full Article
