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.

Head torque specs. Thread Tools. I looked up the torque specs on ls1howto and i was just wondering if anyone knew the torque specs for the last few passes instead of turning the bolt 90 degrees if there are any actual ft lb numbers? I would just feel more comfortable with a number i could torque too. View Public Profile. View iTrader Profile. First stage: Using a torque wrench, tighten the M11 bolts numbered 1 through 10 in sequence to 22 ft lbs. Second stage: Now use a torque angle gauge to add 90 degrees of twist to the same bolts, again in sequence. Final stage: The specifications to use in the stage depend on the style of head bolts that your block uses. Then add 50 degrees of twist to the shorter M11bolts in locations 9 and Once all M11 bolts are secured, use a torque wrench to tighten the M8 bolts numbered in sequence to 22 ft lbs. There is no angle to add to these bolts. I copied this from one of my manuals that I use. If using aftermarket head bolts or studs, refer to the installation intsructions and tightening specifications of the manufacturer.

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. Now, the LS head torque specs ft lbs are easy to understand, but the LS cylinder head bolt torque is also expressed in degrees for the second and third passes. But to do that precisely, you need a degree torque wrench or a degree dial for a standard wrench.

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. The current crop of LS engines is widely regarded as the best small-block pushrod V-8 engine platform currently available. When someone says he or she is looking for a crate engine, the term covers a broad spectrum. Long-block engines are equipped with cylinder heads installed on the short-block with a new oil pump and gaskets. Fully dressed engines are available with all of the aforementioned pieces, including a carburetor and plug wires. True crate engine suppliers have few options available, to keep costs in line.

We review and look at LS1 tuning and highlight the ultimate mods that work. GM LS1 make awesome project cars and with the right modified upgrades like a remap, turbo upgrades and camshafts you will noticeably increase your driving opportunities. The LS1 or Generation III as it's known was very solidly built and with the right mods can make a significant amount of power.

Once all M11 bolts are secured, use a torque wrench to tighten the M8 bolts numbered in sequence to 22 ft lbs. Thats ehat it says in my workshop manual too Find More Posts by crainholio.
