My R clutch (and pressure plate) has started to slip at around 5.8-6k rpm with a K27 turbo. It was fine with my K24 turbo producing 368lb of torque. It has covered 4000 miles.

Has the new VVT head been machined to get the block mating face true? If so do you know if the Enem Cams are designed for a head that is the correct size from the factory and not one that has been machined? With the extra lift the Enem cams provide any material removed from the head may be detrimental to their operation and cause a contact with piston situation should the head be too small.
