I have had several camshafts reprofiled by these people over the years. The best one was the 750F2 cam that was done for me for 'fast road use' when I needed a cam that was not as aggressive as the Yoshimura Road/Track cam but was better than the standard grind. Newmans ground some of the base circle which increased the lift & the duration and made a worthwhile differance over standard.
