Holiday torqued the heads down to 105 lb-ft with moly lube. The high torque rating was due to the 1/2-inch studs. He started with just 40 lb-ft and began in the center and worked his way to the outer ones. Holiday then hit each with 70 lb-ft of torque using the same inside/outside technique. The final go around was done to 105 lb-ft.
