Brand New not remanufactured! Our cylinder heads may not be casted in the USA but we only use the best casting companies to supply our bare castings. Every head we sell goes thru a machine shop in the USA, and gets loaded with premium Inconel valves, Premium Hardened seats, guides and new dual concentric valve springs to keep vibration and harmonics in check. We know this is what makes Our cylinder heads stand out from the crowd. Most of our competitors just import their heads, already loaded with some cheap subpar valve train components that will make them the most profit. We believe in quality over quantity, we only sell what we use in our own shop!
