I have to say that whilst I agree with the idea of avoiding Piper and Kent at all costs, fitting a Newman Cam and Solid Lifters, isn't really a straight-forward DIY job. It takes us 1-2 hours to set the solid followers up on mine and that's with us having done it countless times. It requires most than just the ability to hold a spanner.

Other than that, Newman is the best of what is available out there.
