Inconel with a hard chrome finish. Standard size replacement with oversized head. Dimensions: 1.299" head dia. x 0.2342" stem dia. x 4.055" overall length.

Quality materials and the latest CNC and 3-D computer modelling equipment make sure each and every Kibblewhite Precision Machining valve train component is top of the line.Inconel is a special heat resistant so-called ''Superalloy''. By nature of the material it cannot be black nitrided so it is hard chromed. It has a superior heat resistancy against issues like exhaust valve stem bending; of OEM M8 exhaust valves; without impact. 6mm is thin especially when dealing with extremities as detonation; lean mixtures and poor timing curves. Inconel''s superior heat resistance will maintain its strength longer at higher temperatures; it is therefore used for the thin stems on M8 exhaust valves only.

.405" valve lift. Mild street cam. Smooth idle; more power throughout RPM range. Installs with no headwork.
Gives .470" valve lift on Panhead; .450" on Shovelhead. Basicly an ''A'' grind cam; but with delayed timing to help eliminate ''pinging''. More power than stock cam. Should install with no headwork.
.450" valve lift. Basicly an ''A'' grind cam; but with delayed timing to help eliminate ''pinging''. More power than stock cam. Should install with no headwork.
.450" valve lift. Basicly an ''A'' grind cam; but with delayed timing to help eliminate ''pinging''. More power than stock cam. Should install with no headwork (excl. 81-82). Note: For 81-82 models. The height of original stock H-D valve guides restricts spring travel (and valve lift) to .430" or lower.
Gives .470" valve lift on Panhead; .450" on Shovelhead. Street. More midrange and top end power; smooth idle. Should install with no headwork.
.450" valve lift. Street. More midrange and top end power; smooth idle. Should install with no headwork.
.450" valve lift. Street. More midrange and top end power; smooth idle. Should install with no headwork (excl. 80-81 models). Note: For 81-82 models. The height of original stock H-D valve guides restricts spring travel (and valve lift) to .430" or lower.
Gives .507" valve lift on Panhead; .485" on Shovelhead. Hot street. Much more midrange and top end power. Smooth idle. Good choice for modified motors and small strokers. Solid lifters recommended; spring spacing required.
