I had Tomei Solid Pivots that required machining of the rocker arms. Mazworx recommended I go dual guides at the same time for reliability. I did both and they did it for the same price and the work is FLAWLESS. I wouldn't go anywhere else except Mazworx for this type of machining. Worth the time shipping to them instead of doing it locally.

Sent rockers in, got them back, dropped in and everything was perfect. Thanks
