Could someone please pass along the info on the following : Torque specs and sequence for cylinder heads for 1965 Skylark Gran Sport 401 and torque for rocker shafts . Thank you , George BCA # 38506
George, My Guide to Buick GS lists cylinder head to Block torque at 65-80 ft-lbs, and Rocker arm shaft bracket to cylinder head as 25-35 ft-lbs. As far as the sequence, I guess you could use the sequence for the 455's. Start in the center and work your way out to the ends of the cylinder head in a diagonal pattern. Hope that helps.
