Should have a "M" at the beginning for marine and no 6. MR43LTS

Unless yours is a newer motor then should have AC 41-932

What year is your motor?

the block is an old 4 bolt main with vortec heads,intake,cam,carb and some internals done not quite sure that's how I bougt it.so will those plugs still work?thats what plug we came up with at the auto store.

They are fine for car/truck because the auto is not in a moisture environment. You need alloy plugs because the plugs will rust and for the most part weld them selves to to head
