RACING VALVES PROVEN TO BE BETTER: 
ON THE RACE TRACK, ON THE FLOW BENCH AND IN THE LAB !

No other racing valve on the market has superior material, is lighter or will flow more than the Milodon Megaflow Racing Valve, as proven by multiple independent engine builders and independent laboratories.

  • Premium Quality 21-4N Material on All Megaflow Racing Valves.

  •  Every Milodon Valve is a One-Piece Forging.

  • Megaflow Racing Valves Have a 1600ºF Operating Temperature.

  • Swirl Polished for Flow and Tulipped Valve Heads for Weight Savings. 

  • Undercut Stems for Greatest Valve Flow and Lightness. 

  • Stellite Valve Tips Hardened to 58-60 Rc. Hold Up to High Racing Valve Train Loads. 

  • Compatible with either 7` or 10` retainers.

Independent race valve testing by highly respected head specialists like Joe Mondello of the Joe Mondello Technical School, proves the Megaflow racing valve is second to none, right out of the box.
