The Mitsubishi 4G64 8V cylinder head assembly 171216-1 suits engines that need a fresh top section due to overheating, valve seat wear, or broken casting areas. The head sits straight on the block, and the ports match the original shape, which helps the engine breathe the way it should. Anyone who works on 4G64 engines knows that these motors tend to lose compression once the head gets tired, so replacing the full assembly often solves several issues at once.
When you unpack the head, the surfaces look clean and ready for assembly. The coolant and oil passages sit in the correct places, and the bolt points line up with the factory pattern. A workshop can fit their valve gear without struggling to make parts sit right. Another thing worth noting is that this assembly gives you a stable starting point if the old head has already been skimmed too many times.
