Hi i have just put al my top end back together using groap a head gasket and an arp stud and nut kit i ran it for half an hour to let it warm up and found there to be oil leaking down 1 side under the inlet manifold.Now i followed the arp instructions on tightening the head down (follow spec sequance to 81lbft) but i have been told that you should re torque after first run.should i just re tourqe as in totaly loosen all bolts nad starte again or just torque to a higher torque setting? or non of the above?
