I can tell you are about to embark on somthing you have never done before right? If you are planing on changing exhaust manifolds on any car you must spray the nuts and bolt at least 3 times with a good penatrating oil. Liquid wrench, lock nut, W-D 40 or other penatrating oil. I do it once a day for three seperate days. You will be a lot happier with the results. Heated bolts like exhaust bolts twist off real easy. So be very careful.
