    I would replace them cheap compared to replacing more parts if a valve breaks.

    Are these the new valves or the old ones ? What's the number stamped into the top of the stem ?

    New , 75 valves , or bought a used head and it looks like water was sitting in one exhaust port which these valves came from.

    I'd go ahead and assume the guides need to be done as well. Salt water and boost beat up the exhaust guides which aren't always straight and tight to begin with.
