final torque # in ft lbs for heads

[WS6S]

is there a final number for head torque specs on ls1 heads using gm bolts.i started torquing at 22lbs on the 15 mm bolts then made a second pass at 50 ft lbs.im not sure if i should stop there and just do the 10 mm at 22 ft lbs and be done with them ?

[importhater81]

15 mm bolts first pass torque of 22 ft/lbs
2nd pass of 90 degrees on the 15 mm bolts
3rd pass of 90 on the 15's except fot the 2 on the outside of the head under the valve cover...only 50 degrees on the 3rd pass for those 2 bolts.

Then torque the 10 mm bolts to 22 ft/lbs.

I know you asked for ft/lbs...but the angle meter way is the only way I've ever did them

check out the write up at ls1howto.com it doesn't give you ft/lbs for stockers but does for ARP and it tells you how to torque the stockers.
