What is the primary function of valve guides?

Valve guides ensure that the valve stem moves up and down in a straight line within the cylinder head. This precise movement is critical for the valve to seal properly against the valve seat, preventing compression loss and oil from entering the combustion chamber.

Do these valve guides come with the necessary installation hardware?

This product includes the Brian Crower Valve Guides (Part# BC3927) only. Installation typically requires specialized tools and machining services to press the guides into the cylinder head, and hardware like seals is usually purchased separately.

What is the significance of the 6.6mm size?

The 6.6mm measurement refers to the diameter of the valve stem that the guide is designed to accommodate. Using the correct size ensures a snug fit, which is vital for proper valve operation and sealing.
