Description

The Kibblewhite 20-20776 Exhaust Valve is designed for Twin Cam heads that use 7.0mm valves. These valves are crucial in preventing cracks in the port end of the valve guide boss. With .005" oversize stems, they help re-establish the correct valve stem to valve guide clearance in case of head cracks. To ensure proper sealing, valve guides must be reamed/honed, followed by a valve job. The oversize portion of the valve stem does not extend into the keeper groove area, allowing you to use OEM valve keepers. This exhaust valve, known as Black Diamond, features a base color of black, with a head diameter of 1.575" and a stem diameter of 0.2805". The tulip angle is set at 23?, with a length of 4.510". Perfect for street riding, this valve is sold individually.
