My engine builder used ARP bolts for the deep oil pan I purchased. I'm doing some torquing down right now after 3500 miles of engine break in. The bolts have 5/16" heads except for the corner ones which are 3/8" heads. The CSM says to torque to 12 ft/lb for 5/16" but nothing for the corner ones at 3/8"...should those be torqued to 12 ft/lb as well? thanks very much.

factory specs are 12 for the 5/16 and 8 for the 1/4 the bolt size is not the head size so the larger corner bolts are 12 all the smaller ones are 8 to make it easy.
