I know what they are for arp, but what about stock torque to yeild bolts with stock head gaskets?

5.3, small cam, 918 springs, 7.4 rods, walboro pump, Full built 4l60, 2800-3000 stall, TB spacer, long tubes, cat delete, single 3" exhaust with Aero bullit muffler. Flaco tuned.
Torque all the big bolts to about 24 ft lbs. Then tighten all the big headed bolts 90* farther. Then torque all the big head bolts accept the two shorter ones 90* farther again. Then torque the two shorter big head bolts only 50* farther. Then tighten all the little bolts to 24 ft lbs. Warning... make darn sure there is no coolant in the bolt holes before you start. Warning #2. This was from memory. Do a Google search to be sure and to find out what order to torque them in. Its not hard to find.
He was close...
22 ft/lbs then a 90 degree pass on all 15mm bolts, followed by another 90 degree pass on 8 of the 10 and a 50 degree pass on the last two. Then you torque the 5 10mm bolts to 22 ft/lbs.
Now there is a specific torque sequence you have to follow...which can be found here:

None on M8 bolts until M11 bolts are done with all three passes
22 ft/lbs on all M11 bolts
90 degrees on all M11 bolts
70 degrees on all M11 bolts
22 ft/lbs on all M8 bolts
Not all of these have two shorter M11 bolts and these specs are from GM service information.
