Alloy Cross-Flow Cylinder Head

This head, with computer generated gas flow design, is opening new performance horizons for the venerable B-series engine. Immediate performance and cooling improvements will be noticed even with stock 1 1/2" SUs, but from there the possibilities are still being explored. The heads are completely assembled with standard size valves, bronze guides and hardened seats. The exhaust ports are in the original location so that regular early manifolds or headers may be used. We recommend the stainless header (459-015) as the manifold is highly visible. The head requires a new four-branch intake manifold and matching carburetors. You may choose from the three choices of manifolds and carburetors below. The Weber DCOE manifold kit and 45 DCOE carbs off the highest flow possible for maximum power potential in modified engines.

There is no provision for emission connections and some modifications will be required for best operation. Manifold kits do contain intake gaskets and some linkage components, but due to the variety of applications, some fabrication may be required. Accelerator cables are not supplied and must be fabricated. Valve interference must be checked on pre-18V blocks.
