Brand New 3406E LOADED Universal Stage 3 Cylinder Head. This head will work with both Acert and non-Acert engines alike! From 3406E to C15, to Acert applications you are all set! They are better than OEM quality containing 5% more nickel content in the casting material. 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 3 cylinder head is an upgrade from the stage 2 cylinder head. The difference is that BOTH the exhaust AND intake 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.
