This is due to higher friction on the studs as well inconsistencies in clamping force of fasteners when motor oil or other low quality lubricants are used.

Installation Instructions: Following the manufacturers recommended torque sequence tighten nuts steps 1-3 Step 1: Tighten to 30 ft-lbs. Install the cylinder head and check for binding or misalignment. To ensure proper thread engagement and accurate torque readings, clean ALL threads in the block.

Clean and inspect all hardware prior to installation. These head studs provide various benefits upon installation, such as improved clamping force and better sealing of the gasket, ultimately preventing gasket failure.
