Description

These heat-treated valve locks feature a 7-degree lock style and a 1-groove design. They are compatible with 8mm valve stems and are specifically designed for Chevy LS1 engines.

This product includes two valve locks, which is enough to service one valve. The locks are machined for precision and do not have a recessed design for a lash cap. They are sold as a pair. Some parts may not be legal for use in California or other states with similar laws and regulations.
