Review on Genuine GM Cylinder 🧠 Head Gasket - Part #12589227 by Roy Whetstone

Revainrating 1 out of 5

They are not suitable for 6.0 engines!

They are not designed to repair 6.0 gas engines. Built in and wrong. The lip overhangs the cylinder wall by 0.007. Buyer beware as it damaged my engine.

Pros
  • Replacement parts
Cons
  • No instructions
