Yes, Just because it is black doesn't mean its not stainless. Put a magnet on it SS is non magnetic. The 4" risers with the short mount bolts are
SS. The ones with long bolts that reach to the top are cast iron.

The Aluminum manifolds usually have a hose that directs the water around the gasket. If the tailpiece gaskets only seal exhaust your good. If by chance you find a brand { I don't know of any} that the tailpiece gasket seals exhaust AND water I would stay away from it.

Confirmed, those are stainless risers. I currently have a real nice pair of used ones that have been collecting dust for about 6 years in my barn. On the side it reads:

Mercruiser
stainless steel

Believe that set came off of a 92' Baja....

Thanks again Strip...

I thought about adding some high temp also... it looks like I can get a seal. I just gotta get those dang bolts out of the head.... any suggestions....

Be well..
