Default Exhaust flange gasket recommendations

When I first switched my '63 Bonneville (389) back to duals (stainless) in '86, I had a real Dickens of a time getting the pipes and the flanges to line up squarely.

More recently, the engine was rebuilt and everything put back together (not by me). I have a noticeable leak on (I think) the passenger side, and it sounds like it's right up front. The likeliest culprit is the flange. What is everyone using these days for good sealing? Extra thick gaskets? Brands?

TIA
