Most high performance engines today require the use of larger-than-stock diameter valve springs. This 1.680" Spring Seat Cutter from COMP Cams will allow the engine builder to machine the cylinder head to the proper size for your spring. Each cutter requires the use of an arbor/pilot, which are available in three different sizes.

This valve seat cutter allows you to enlarge the cylinder head spring pocket to 1.680" outer diameter while reducing the outer diameter of the valve guide to .630".

The COMP Cams philosophy has never changed: make the highest performing products possible and lead the industry in technological development. One thing COMP Cams has never forgotten: Performance is defined by what happens out on the race track. Because no matter what happens on a dyno or in a computer model, if that theoretical performance doesn't translate into real-life results, then the mission isnat completed. COMP Cams spends thousands of hours working with race teams to make sure COMP Cams products provide unmatched performance and reliability. That's why every COMP Cams product offers the highest performance standards. COMP Cams competitive drive culminates at the track and in Victory Lane. COMP Cams has produced more champions than any other camshaft manufacturer.
