20-2033C KPMI, exhaust valve guide. Cast iron. +.003"

When you are working on a Panhead or an early 74-inch Shovelhead, managing exhaust heat is a top priority for engine longevity. These Kibblewhite cast iron exhaust valve guides are designed for maximum durability and wear resistance, especially in long-distance touring applications where heat soak is a constant factor. This specific guide is +.003 inch oversize to ensure a perfect press-fit in heads that have been previously serviced or bored. They fit 1948 to 1965 Panhead models as well as 1966 to 1978 1200cc Shovelheads. Using cast iron ensures a long service life and consistent performance, maintaining the tight tolerances required for a healthy, high-performing vintage valvetrain.
