Description:

Oversized Valves: The oversized head diameter is designed specifically for each application,
significantly improving the flow rate.

Waisted Stem: The waisted stem allows a greater volume of air/gases to enter
and exit the combustion chamber as the valve extends. (not available on some models)

Engine Specific Design: Each valve is designed and precision machined specifically
for the intended engine/application. The head, face, stem and lock groove designs
have also been optimized to enhance sealing performance, efficiency and durability.

Heat Resistance and Durability:
Intake valve: The intake valves are made using SUH35 HEAT RESISTANT STEEL which is more commonly used to make exhaust valves. These are then coated with a special formula that further improves
the valves' resistance to heat, wear and corrosion.
Exhaust valve: In order to withstand temperatures of up to around 1000C, the exhaust valves are made using a nickel based heat resistant alloy, INCONEL 751.
