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. This ensures even pressure distribution and helps prevent the spring from shifting or wearing unevenly.

What does the '1.550' in the product name refer to?

The '1.550' refers to the internal diameter (ID) of the valve spring seat in inches. This measurement is important for ensuring it correctly fits the valve spring you are using.

Are these seats sold individually or as a set?

This product is sold as a set of sixteen (16) valve spring seats. This quantity is typically enough for a complete engine with 16 valves (8 intake and 8 exhaust).
