The 18cc Cylinder head kit includes an 18cc cylinder head, a set of valves and retainers. NO valve springs are included, please purchase separately.
The 18cc Cylinder Head is a dedicated cylinder head for our ZR28 Racing engine model. It features much thicker intake and exhaust ports and a shallower combustion chamber. The intake port is slightly bigger at 28mm and the exhaust port is 25mm.
Please note that standard exhausts and intake manifolds that fit Honda GX200 clone cylinder heads will NOT fit the intake port and exhaust ports on the 18cc cylinder head.
We offer compatible intake manifold and exhaust header in our store.
