We replace your worn stock valve seats and guides with high performance valve seats and guides. We use a innovative copper alloy valve seat material which dissipates heat from the valves to the seat much quicker than the stock material. Our guides are made from a nickel-aluminum-bronze which is reamed and honed to exacting tolerances to insure precise valve stem control. Like our valve seats, our valve guide material dissipates heat significantly quicker than the stock guide material.
