Which Exhaust gasket on my Mercruiser 4.3L EFI 1998

[juruca]

Hi Guys,

I have to replace my one piece exhaust manifolds.
The new 2-piece set comes with many gasket types, even closed types.
I checked many things on internet and youtube but still confused which to use.
Who can tell me which gaskets to use and why ?
I don't use risers.

Thx a lot

Ayuh,.... Most likely the 2 slot gaskets, but post a picture of yer t-stat assembly,.....
It depends on whether yer motor runs warm manifold plumbin', or cold manifold plumbin',....
