This additional nickel content prevents the cylinder head from cracking in between the valves. Additionally, the coolant passages have been enlarged by 30%, and inner ribs have been reinforced to reduce heat stress. This stage 2 cylinder head is an upgrade from the standard cylinder head. The difference is that the exhaust valves in this cylinder head have all been upgraded to inconel valves. This major performance improvement increases the capacity of the valves to endure higher temperatures as well as heightened pressure.
