WINONA, MN — Goodson Tools & Supplies for Engine Builders had designed and manufactured a new style of valve seat stone holders called New Generation Valve Seat Stone Holders. These holders are a simplification of the stone holder as we know it.

According to Dave Monyhan, “Our goal with the New Generation Stone Holders is to provide you with stone holder that fits your existing pilots. Whether you use .375”, .385”, .389” or .437" top pilot, you can find a stone holder that works.”

The New Generation Stone Holders are available in spline (star) and hex drive with either 11/16” x 16 or 13/16” x 13 thread to fit the most popular valve seat stones in the market.
