High lift Rally Cams to suit racing 4AGE 16V engines with big valves, increased compression and well designed intake and exhaust system. Good mid-high rpm power. 'HV' high velocity cam profile, more cam sweep area than the stock shim will allow. Must convert to shimless or shim under bucket style lifter. Kelford Cams recommends KVS101-BT valve spring._x000D_\n
