Anthony,
My goal is only to send someone in the "best" direction, albeit your suggestion is still the "right" direction. Although some of us have become quite experienced replacing head gaskets on a regular basis, not everyone wants to experience these reliability issues if they can avoid it. It is always best to try and avoid the trial and error process if possible, as it makes working on the vehicle, and owning it in general, more enjoyable.
Although you were lucky with your block suface being free of manufacturer's defect, a lot of the 3.8L blocks do have block surface issues that should be resolved through the decking process. With the power you're making, I think it's fair to say that you're lucky if you are running stock bolts and a factory block without leakage issues, from either the trueness of the surface, or the head lifting slightly under boost.
As for re-using the gaskets, that's not something I would recommend to others either. Although the gaskets look fine when they come out, they still go through a crushing process when the heads are torqued down, and should not be re-used. Again, just because one person has success with it, doesn't mean that everyone should, or will be so fortunate. Chris Wise had been in contact with Fel-Pro regarding these gaskets when he started using them, and I believe they told him not to re-use them.
There is no point sending someone down the path to failure. These cars are not worth taking shortcuts with.
