This alloy is\n ideal for extremely high boosted applications where the exhaust gas \ntemperatures reach what seem like unthinkable levels.\n\nManley stainless valves are suitable for all applications ranging from \nthe mild street performer to the jaw dropping 1000+ horsepower race cars\n competing at the drag strip or drifting events.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003ePart Number:\u003c\/strong\u003e\n                                man11158-8                            \u003cstrong\u003eDescription:\u003c\/strong\u003e\n                                Race Series Valves; Intake; Set of 8                            \u003cstrong\u003eHead Diameter:\u003c\/strong\u003e\n                                35mm                            \u003cstrong\u003eMargin:\u003c\/strong\u003e\n                                .050\"                            \u003cstrong\u003eO\/A Length:\u003c\/strong\u003e\n                                101.96mm                            \u003cstrong\u003eSeat Width:\u003c\/strong\u003e\n                                .075\"                            \u003cstrong\u003eStem Diameter:\u003c\/strong\u003e\n                                5.5mm\/.2165‚Äù                            \u003cstrong\u003eTip Length:\u003c\/strong\u003e\n                                2.49mm                            \u003cstrong\u003eTop of Head:\u003c\/strong\u003e\n                                Flat Face                            \u003cstrong\u003eUnderhead Angle\/Radius:\u003c\/strong\u003e\n                                Pro Flo: 22¬∞ x 5\/16\"                            \u003cstrong\u003eEngine Application:\u003c\/strong\u003e\n                                tC                            \u003cstrong\u003eEngine Detail -
