I used the left side as well. I didn't actually use a torque wrench. I used my cordless makita 1/4" drive impact. It hasn't had an issue since. The only 2 things I torque down using my torque wrenches were the billet rod bolts and fly wheel bolt. After watching several YouTube videos of a couple guys building these little engines, they didn't seem to worry about torquing down certain bolts that a lot of the guys on here have. If it doesn't hold, I'm out a whopping $3 for a headgasket lol
