There is either a 1.4L or 1.8L in a Sonic the figures are for a 1.8L as you said it is an LS. You need new bolts for cylinder hear, connecting rod, and flywheel as well as main bearing as they are torque to yield bolts. Meaning old ones can break prior to getting torque. See pictures for settings the en tool they are talking about is a $5,000.00 torque wrench that you just set it and go you can do the same with a regular torque wrench and a degree wheel to set the torque to spec. Do not forget to add rtv next to rear main bearing or you will have a leak.
