Now available for purchase OR rental! A must for your hardcore engine build. Another Massive exclusive!!! No one else offers these for the Duratec!!! The torque from a properly fastened cylinder head can impart significant distortion to the bore. Rings do not seal properly and scuffing is often the case if the engine overheats. By installi
