278°-272° split lobe design on the inlet. High lift cams for improved port flow and more top end power. Suits 64mm+ turbos. Ideal for drift, strip or race cars where high rpm power is important. Cylinder head requires machining for clearance of high lift cam lobes. Kelford Cams recommends valve spring KVS20 (non-NVCS heads) / KVS25R (NVCS heads).
