Thanks Steve. That’s exactly what I needed to know.

Thanks Steve. I’m primarily concerned with valve seats. I’m not sure if it applies to the mechanical 8.3 or if it was later. It looks as if Cummins changed the material at some point. If I compare head sn on quick serve with those in the article on Sbmar, the numbers don’t match. No sea trial yet. Getting my ducks in a row. Single engine in a working/gill netter type boat.
