“All SPA Turbo's cylinder head stud sets includes 1 pack of CMD's anti scoring lube #3.

Designed for extreme pressure applications, it’s perfect for cylinder head studs assembly, as it stands pressure values of 40,000 to 50,000 psi, which helps to reduce thread friction and ensure that the torque applied is used to properly stretch the bolts.”
