    Michigan Motorsports' stainless valves are a great upgrade for your factory LS cylinder heads. Made from high strength 21-4N Stainless Alloy, these one-piece forgings feature hard chrome plated stems and hardened tips for durability. Undercut stems and swirl polishing improve flow over the OEM GM valves and standard aftermarket replacements. These valves are designed to be a direct drop-in replacement for the factory 1.890" Intake Valves and 1.55" Exhaust Valves on the applications listed above.
