REVTECH INTAKE VALVE OVERSIZE-1.940 DIAMETER FITS CCI REVTECH HEADS CUSTOM FIT IN ALL OTHERS
Source: Custom Chrome
RevTech® valves combine the latest in engineering (including the ability to deliver high-performance with no lead or low lead fuels) and the widest range of applications possible with the fewest part numbers. The valves are true, one-piece stainless steel, and the stems are completely nitrided for superior resistance to galling at high cylinder head temperatures. The valve stem tip, rather than just being a swaged-on button, is a fully-supported cup of stellite, formed by first machining a recess into the stem, then filling it with super-hard stellite material. The heat-treated material forming the cup firmly supports the stellite and distributes the impact shock of the rocker arm over a wider area. Each valve is clearly marked with the part number on the stem. Each part number replaces several Original Equipment numbers to simplify stocking. For example, the stems on the late Shovelhead exhaust valves are machined to .375" diameter, which fits all early and late-style valve guides when new guides are correctly reamed to final size. With a minimum number of valves, all 1948-1981 Big Twin and Sportster® motors can be upgraded to run on unleaded or low lead fuels with your own choice of valve guide material. Sold each.
