These are the stock bolt torque specs, if you are running ARP bolts then refer to the instructions that came with the bolts for their torque specs. The column to the right on the guide shows a "degree" section, this means the bolts that are being used in that application are Torque To Yield TTY. TTY bolts are one time use only becuase they stretch after they have been torqued. These bolts allow more clamping force when two metals are expanding and contracting, the bolt will move with it instead of fighting against and potentinally breaking. What this means to you? This means this guide is a one stop shop to give you common questions on the torque specs of these bolts. No more just sending her home with two ugga ugga's. Be smart.

I wouldn't, they aren't designed for it and the torque specs are factoring that you won't be using such.

The cylinder head gasket is one of the most over-engineered and stressed components in an internal combustion engine. The LS head bolt torque is pretty complicated. First of all, the head bolts for all LS engines are TTY torque to yield which means they cannot be reused once they are tightened to the correct torque specs. Such bolts stretch out too much after the initial tightening that they become too long and fragile to reach such high torque again and will most likely snap. Next, all LS cylinder heads have a tightening sequence which is just as important as bolt torque. Furthermore, multiple passes mean you need to tighten the correct bolts in the right sequence to a specific torque, then repeat the process again with a different torque as many times as there are passes.

Crate engines are typically the most cost-effective way to add horsepower with minimal labor. The same goes for transplanting an LS-series engine into your Shark, and you could conceivably save a few bucks buying in bulk, so to speak. You have many crate engine options, including Chevy small-block and big-block.
