If the original manifolds have never been off be prepared to tear the head off because one bolt will inevitably snap (my experience, hopefully yours will not be so ugly). If they have been off before, unless antisieze was used, AT LEAST one will break off or round off the head - something about taking one out and putting it back in that guarantees they will stick.

The tabbed and circlipped header bolts usually have an allen inset head to help get them tightened down but there is always one or two tabs that will have to be ground down to fit properly.

Old trick I learned years ago is to pre-soak the header gaskets in cold water overnight prior to installing them. Water makes them swell slightly and adhere when they get heated the first time. Of course, you then have to retighten them after one heat cycle to get them tight enough to keep from blowing out. Make sure the head surface is absolutely clean before putting the headers on. It only takes one little piece of old gasket to screw up the seal.

Good luck and save the liquid refreshment till after the cussin' is done ;>)
