The simple stuff (intake, header, exhaust) don't really require a torque wrench but when you start adjusting your valves, opening up the head in any way, or if you have aftermarket rims, then you will definately need to use a torque wrench. Its a good investment.
I would say get one. They are a necessity when working with the engine. But $180??? That a little expensive!!! I've seen them at Sears for much cheaper. Most expensive one they had was like $100. Get the torque wrench, but not for 180. Look around and get a cheaper one.
no the cheaper one is just a needle and gauge. basically you pust, watch needle move, and stop when it gets to wear you want. i use this for unimportant stuff just to be safe, and the better one for important stuff.
$180? was that Snap-on? hmm..anyways I would agree with the Lot with Craftsman..Been using it on american cars since I was little helping my dad..We've never had an issue, and yes owned a torque wrench..My personal most frequent use is changing our Rims off street tires for Racing Slicks so we can autocross..
