Can a mk2 cylinder head fit on a mk1?

Yes, a Mk2 cylinder head can fit on a Mk1 engine, but modifications may be necessary to ensure compatibility. The Mk2 head typically has different port shapes and sizes, which could affect performance and require adjustments to the intake and exhaust systems. Additionally, consider the differences in engine management systems between the two models, as this might affect overall functionality. Always consult specific technical resources or a professional mechanic for precise guidance.
