Comp Cams Spring Seat & Guide Cutters

Product images may differ from actual product appearance.

Most high performance engines today require the use of larger-than-stock diameter valve springs. These tools from Comp Cams will allow the engine builder to machine the cylinder head to the proper size for your spring. Each cutter required the use of an arbor/pilot, which is available in three different sizes. These arbor/pilots also will work with the valve guide cutters used for shortening the guide for a high lift cam or installing a Comp Cams Teflon seal for oil control.
