Understanding Valve Design and AlloysFor many late model engines (and performance engines), the intake valves are made of an alloy called Silchrome 1 (Sil 1) that contains 8.5 percent chromium. Exhaust valves may be made from a martensitic steel with chrome and silicon alloys, or a two-piece valve with a stainless steel head and martensitic steel stem. On applications that have
