All charts I view say 90-100 ftlbs. The head bolts are 7/16 and usually a 7/16 bolt require 65 ftlbs. When reviewing allowable torque for various size bolts even ARP they recommend 65-70 ftlbs for 7/16. At 100 ftlbs it looks like the 7/16 would loose "clamping" pressure because of excess stretch. ANY COMMENTS?
