At some point, my roadkill 66 383 will need an exhaust, and considering headers. Just wondering what your experience has been in getting the twelve errant bolts out in one piece. Mine is pretty original and has not suffered too much from the weather, in general. So, just trying to prep myself for an easy out. I like the tried and true back and forth on old bolts....but even this may not suffice. Whaddayathink.
