Manley Extreme Duty Series performance steel valves are a great choice for supercharged, alcohol-burning, or high-revving engines.

All valves are made from the best stainless steel available, with chrome stems and hardened valve tips. Extreme Duty Series valves are swirl-polished and fully machined and available with either undercut heads or straight stems.
