ABSTRACT:
A valve spring seat is disclosed having at least one annular flange in facing relationship with a surface of an engine head. The flange may be part of a valve seal retainer. A radial cut extending inwardly from the radially outermost edge of the flange to an intermediate position on the flange forms two opposing free edges. The first edge is bent in a first longitudinal direction to form a first tab, and the second edge is bent in a second, opposite longitudinal direction to form a second tab. The first tab engages at least one coil of the valve spring, and the second tab engages the cylinder head to prevent rotation of the spring during reciprocation of the spring.
