edit: Do you have a socket set and a torque wrench? I definitely recommend using a torque wrench on the head studs and every other bolt as well. Here's a link to a cheap torque wrench that will work fine: http://www.harborfreight.com/3-8-eig...rench-807.html
A foot pound torque wrench will get you by, but I'd recommend a INCH pound torque wrench.
1/4" Torque Wrench - 20-200 in. lbs.
Unless you want to get into automotive engines and the like, then the FOOT pounds might serve you better. The INCH pounds will be more useful for a noob.
