I got sick of messing with the cast iron two or three piece exhaust manifolds and went stainless about six years ago. Expensive, but worth it because: 1) No gaskets. They're one piece hand welded 304 stainless manifold/risers. 2) They provide much better performance, because they're an equal length tubular header design. 3) They weigh a LOT less than the cast iron pieces. On my Chrysler small block, I went from 82 pounds per side to 14 pounds per side. 4) They don't wear out. Because they're 304 stainless, they don't rust. If they crack or dent or otherwise have a bad spot, a good TIG welder can repair them good as new quite easily and cheaply. 5) Because they're hand welded for each customer, you can order them however you like them, with hose fittings, etc where and how you want them. I ordered mine with fresh water cooling and then used them to heat the boat. I have a Red Dot heater plumbed into each manifold, one to heat the cabin and the other to heat the cockpit on my 27 Express cruiser. The cockpit heater is ducted onto the windshield so that in my SE Alaska winters I can have good visibility in the ubiquitous 34 degree horizontal rain 'showers'.
Customer service was pretty good. I ordered them for my boat and, in less than two weeks from the time I placed the order, they were custom made in Australia and delivered to me in SE Alaska. At that time, cost was just under two thousand a pair including shipping. I pulled the zinc and looked inside when I rebuilt the engine this year and they're still good as new six years on.

Over the years I've experienced seeping between the two maniflod pieces. I've replaced gaskets and resealed them but the continue to seep. I 'm planning on removing them again.This timet I plan on resurfacing the gasket sealing surfaces. Does anyone have a reccomendation for a really good gasket sealant? The last time I used Permatex Form-A-Gasket because I'd had good experieances in the past but, it didn't work the last time. any help would be appreciated.
