LS6 Intake Torque Problem Well, I'm putting my LS6 intake back on and when looking at the torque specs, I found you are suppose to torque it in two sequences, first at 44 inch pounds and then again at 89 inch pounds. Well the smallest torque wrench I own only goes down to 10 foot pounds. 
Is this pretty crucial to sealing? Do I need to go buy an inch pound torque wrench or can I get by with snug.

i dont think its a must. id just torque them down lightly first, then go ahead and torque them down harder and thats about it. am installing mine this week. it wont hurt to know for sure tho lol
YES, it is very important to torque the intake down to the correct spec,, You need an inch pound torque wrench, most of them are 1/4 inch drive. You can just snug them most guys do, but the tool definately is the way to go. I dont see your location, but if you are close to me, I would let you borrow mine I am in NRH the north side of Fort Worth.

I ended up borrowing an inch-pound torque wrench. It only cost me a case of beer, and that was my choice 
. From playing with the intake bolts I can definitely see that it would have been impossible (for me anyway) to gauge the torque by feel. There was only about a 1/2-3/4 turn difference between the first round of 44in-lbs and the second at 89in-lbs!

If you do much work on these cars, you'll find you use it every now and then, in critical applications (oil pan, intake, etc.)

If something says in-lbs you better get out your in-lbs tq wrench (and make sure it is calibrated properly)
When I was assembling my wilwood rotors I didn't have one so I figured snug was good enough with a 10mm box end wrench (I mean they called for like 89in-lbs or so, and it' snot like I can apply 50ft-lbs with a 10mm wrench).
Anyways, long story short, after sheering 3 of the bolt heads right off I figured better buy an in-lbs torque wrench and do it again

Yeah, worth the investment, just be sure you get one that has settings low enough for your needs. I had one and the next thing I know it didn't set lower than 90 in-lbs so I had to search for another one and ended up getting a cheap one off ebay because none of the hardware stores or autoshops had anything that small locally.
