I'm about to put my new exhaust manifolds and risers on and noticed that the Sierra gaskets for the riser are very different than the OEM Volvos. The Sierras are thick and look like they can deal with imperfections. The OEM Volvos are a thin meta gasket with a small rubber bump separating the water passages from the exhaust. The Sierras might work better for surfaces with imperfections, but I've got new surfaces. I've researched all the archives and can't tell which ones to go with when dealing with new surfaces.
Also, the spark plugs that were in the boat are a Champion 7103's. I can't find any reference if these are even the right ones to use. VP part numbers for the spark plug usually take me to sites that sell them for $9 a piece! Napa is giving me these as options. The motor is from 1997.
