Unhappy Does a 4.6L/281 displacement exist?

Sounds dumb but all online websites that show specs for my car state that it has a 281 displacement. I can't find valve covers for that displacement on AM or LMR. :/
289,302,351 are the only ones they have valve covers for.

Help me clarify. Please and thank you.

4.6 liters equates to 281 cu/inches. well sorta, liters are kinda vague because the numbers can be rounded up or down since you wont say 4.6047 liters for example...

you want valve covers for a 4.6 liter. you need to find out if you have romeo or windsor heads though. go out to your car and count the number of bolts that hold the cover on, if its 13 on one side and 14 on the other, you have windsor heads. if you have 11 bolts on both sides, you have romeo heads. then you simply find the valve covers to match.

BBK romeo aftermarket valve covers:

BBK windsor aftermarket valve covers:

More than likely you have the romeo heads and valve covers unless the heads have been changed before.
