Milodon Megaflow Competition Valves

4.65 out of 5 stars 17 Customer Reviews

No other racing valve on the market has superior materials, is lighter or will flow more than Milodon Megaflow racing valves, as proven by multiple independent engine builders and independent laboratories. These competition valves are forged from one piece of 21-4N stainless steel. They have swirl-polished heads, undercut stems for better gas flow, and tulipped underhead areas for weight savings. With their hardened stellite tips and 1,600 degree F temperature capabilities, they can withstand both high-heat and high-valvetrain stress loads.
