Research and race experience over the last 4 years has resulted in the launch of this updated design 1000cc MAE head.
Note the shape of the combustion chamber " The Westlake point" aiding swirl and burn properties. The valves are completely unshrouded. The combustion volume gives 12.0:1 with flat top pistons and without a major amount of metal removed from the head surface. The cooling "bananas" are modified thus taking gasket problems away.
Choice of valves, this has 1.4 inlet and 1.25 exhaust (1.45 and 1.3 are available both with 9/32 stems/bronze guides.
Spring pressure is 90lbs on the seat and 210lbs open with an A8 cam.
All these heads are from an original 105E casting so are legal everywhere.
When complete these heads are vacuum resin impregnated for positive sealing and tested at 60psi with water at 80c.
Complete ready to install
