A popular upgrade to allow more lift or accommodate a more aggressive roller camshaft when using traditional Small Block Chevrolet heads is to retro-fit them with LS-style valve springs. This tool will allow you to machine the cylinder heads for the correct diameter valve spring. The durable carbide cutting tip material ensures precision and accuracy. The cutter requires the use of an arbor pilot, which is available in four different sizes.
