Crossflow Alloy Cylinder Head
These Crossflow (in-line oil feed) aluminium cylinder heads (suitable for both MGA & MGBs) give up to 30% more flow, plus they have a much improved flow water flow for increased cooling.

They are machined to 37cc combustion chambers and supplied fully loaded with bronze valve guides, lead free valve seats, valves, springs and caps. They are also machined to use in-line oil feed rocker gear (not included), see below for roller rocker details.

These cylinder heads use standard exhaust port configuration and are compatible with our Sports extractor exhaust manifolds, ideal for gaining extra BHP. Inlet manifolds are available to suit either SU or Weber carburettors, see below.

We recommend that you replace cylinder head studs and use NEW hardware where possible during installation to ensure the heads are as a good a fit as possible. We also suggest you fit new, uprated, flanged cylinder head nuts ( 51K1193B). When fitting an Aluminium head, you MUST run with 100% Anti-Freeze/Summer Coolant which contains the correct inhibitors to prevent corrosion and electrolytic reaction.

The heater valve must be replaced with the type detailed below. Please ensure the head is cleaned thoroughly prior to installation.

We also offer a Webcon full EFI & Cross Flow cylinder head conversion kit.
