272°-264° split lobe design on the inlet. Short duration and high lift cams for improved port flow and more top end power. Suits 64mm-72mm turbos. Ideal for high power street/drift or track cars. Cylinder head requires machining for clearance of high lift cam lobes. Kelford Cams recommend valve spring KVS20 (non-NVCS heads) / KVS25R (NVCS heads).
