Some obvious answers are carb, fuel pump, alternator, anything electrical or dealing with fuel delivery.
Anything special about intake manifolds or heads that makes them "marine" or are street applications fine?
10 years ago I would have replaced them all with auto parts because they are cheaper, but 10 years ago I was kinda stupid. Safety didnt seem as important.
You have it right. Basically, electricals, fuel pump, carb.
Intake manifold and heads are automotive.
