Hello again, I was wondering if anyone knew the torque spec for arp head bolts for a 351w? I'm using 10w-30 motor oil instead of their lube and these are the 6 point/170,000 psi hp head bolts. I searched for hours on the web but can only turn up info on the 7/16" bolts. On arps site they say to torque them to 110ft/lbs. Now I hear that with 302(7/16") head bolts you torque them to 85ft/lbs. instead of the 70ft/lbs listed for their lube. Knowing that would I want to torque mine to something like 130ft/lbs since mine say 110ft/lbs with the lube? I want to make sure I don't want to over compress the head gasket or mess up the threads.
Also I hear some say that you should tighten and then loosen the head bolts 3 times? I think arp says to do that 5 times??? These have been torqued to 100ft/lbs once before but one of the oil rings got messed up and I had to tear the motor back down. If I loosen then re-torque the head bolts would I not ruin the head gasket? If I loosen and tighten them back one at a time would that help or would I still mess up the head gasket? I threw away all of my old head gaskets so I'd have to buy new ones if I have to do all this and my gaskets do get messed up in the process. Could I put the head bolts on with a bunch of washers under them instead of the head and loosen and re-torque them 3 times? That way my head gasket doesn't get messed up? Thanks for any help on this
