Manifold/Riser gasket question

[tlcausey]

Hello, I've got a 1996 mercruiser 5.7 engine. I'm replacing the exhaust manifolds and riser/elbows and they have a 3" spacer between them.My question is which gasket to use. I've attached a picture of what I have. The new manifolds come with 2 gaskets pictured on top with 2 slots and 2 small holes, the 3" spacers came with 4 gaskets seen at the bottom of the picture with 4 slots. I'm thinking the gasket with 2 slots goes between the manifold and the spacer and the gasket with 4 slots goes between the spacer and riser but just want to be sure. Any advise would be greatly appreciated, thanks.

Top one is used with standard raw water cooling, bottom is used when you also have a riser installed between the manifold and elbow

the open gasket (4 slots) goes between the manifold and the 3 inch extention,
the restricted one (2 slots, 2 holes) goes between the 3 inch extention and the riser

I'd throw them GLM gaskets away and get some quiksilvers! OEM. I know that's not your question but with something as important as a manifold riser seal I'd want the best.

I'm a big proponent of good gaskets myself. But those appear to be the correct style. If they are metal with a coating of graphite they are the good stuff.
