Description
Improved cylinder head flow means more power. Our Alloy Cylinder Heads for MGA’s and MGB’s feature nickel-steel valve seats and silicon-bronze valve guides for use with unleaded fuel. The aluminum component saves weight and improves cooling, while the revised porting and combustion chamber increases efficiency. Heads are smog legal with stock emission control equipment. If required, water choke port must be drilled. Valve interference must be checked on pre-18V blocks. Requires UNC manifold studs #328-765, not included.
