i always go 75 ft pounds,,and have never had any problems with them,,and i have built about 300 Chevy engines in the past 35 yrs,,so i guess i must be doing something right,,besides i own a repair shop,,and i have to be accurate on these things or i get comebacks,,and they cost you money,,hope this helps.,,,also start from the middle and go out,,never try and get all the torque the first round.

70-75 ft lbs. be sure you go in the right order. and torque them in steps. First torque them in order to 25 ft lbs, then start over and torque them to 50 ft lbs, then start over again and finish them off to 70-75 ft lbs. Be sure to coat the threads in engine oil before you screw the bolts in too. The will not torque right if the threads are dry.
