V8 engines. Milodon Street stainless valves are one-piece forged valves that are the perfect replacements for use in your street, Circle Track, or bracket racing engine. The intake valves are forged from quality HNV8 stainless steel, while the exhaust valves are forged from premium 21-4N material to withstand the extra heat and stress. The valves have hard-chromed stems and machined heads. They are designed to take a beating, with large seat margins which allows more than one regrind.
