Description
This Manley Extreme Duty exhaust valve family is intended for Ford Coyote 5.0L 31.5mm builds where valve dimensions need to be matched deliberately to the cylinder head, seat work, and valvetrain geometry. Use the exact Manley part number shown below to distinguish this product from similar valves offered for the same or related engine family.
If the Ford Coyote 5.0L 31.5mm cylinder head has been ported, fitted with oversized seats, or changed from its original valvetrain layout, confirm the required valve measurements after machining rather than using a stock-size assumption.
