The danger of snapping the head off of these is so good, and with nasty consequences, that I'd not use a torque wrench. I used a 1/4" drive and just snugged the bolts tight to the left by feel. No need for the ultimate tightness as the normal rotation of the cams is in the direction to keep these tightening.
