Exhaust valves, from left to right: stock, stock undercut exhaust, and Ferrea (all sizes 1.50 inch). Unlike the intake valve, there are some advantages to retaining the stock exhaust valve, but only if it's undercut (center). Merkel found that a 25* undercut on the stock exhaust valve provided almost the same amount of flow through .500-inch lift as the aftermarket Ferrea. Beyond .500 inch, the Ferrea performed better, but this would only benefit a solid roller cam race motor. The quality of the metallurgy aside, the stock replacement stainless exhaust valves are considerably cheaper than race pieces. This engine is using the Ferrea because the owner already had them from an old motor, but the undercut stock unit would work just as well. View Related Article
