p.mole, fantastic information, you have completed the process that I have started, with results that I would be very happy with. Could you list out the changes you made to the stock engine as they appear to be extensive and I would like to make sure I have allowed sufficient funds! I currently have a vvc head which I am flowing, Piper vvc blanking kit, Piper verniers, I need to purchase the Piper (285H) vvc cam kit which removes the vvc mechanism. I will also go for the hydraulic cam version, but would appreciate advice from anyone with greater knowledge and my logic is that I only need the car for fast road use.
