What is the purpose of a valve spring seat?

A valve spring seat provides a flat, stable surface for the valve spring to rest on within the cylinder head. It ensures the spring is properly aligned and supported, which is essential for consistent valve operation and preventing spring damage.

What does the 1.500 inch inner diameter refer to?

The 1.500 inch inner diameter specifies the size of the seat itself, designed to accommodate valve springs with a corresponding outer diameter. This ensures a snug and correct fit for optimal performance.

Are these valve spring seats sold individually or as a set?

These valve spring seats are sold in a set of 16, as indicated by the '-16' in the part number. This quantity is typically enough for a complete V8 engine rebuild.
