What is the purpose of a valve spring seat?

A valve spring seat provides a stable base for the valve spring to rest on. It ensures the spring is properly positioned and maintains consistent pressure, which is critical for proper valvetrain operation and preventing issues like valve float.

What does the 1.550" OD spec mean?

The 1.550" OD refers to the outer diameter of the spring seat itself. This measurement is important for ensuring it correctly matches the diameter of the valve spring you are using, as well as the cylinder head's spring pocket.

Are these seats sold individually or as a set?

The part number 42122-16 is for a set of 16 valve spring seats, which is typically enough for a V8 engine.
