As a generalization...no.

Unlike the consistently riveted leading edge of the 427 Comp cars, the vast majority of 289 competition cars did not have that add-on.

The exceptions...It is curious that the Sebring cars (CSX2127,2128, 2129) had the hood rivets, but in a smaller number than the 427 patterns.

They also were seen on FIA car CSX2345, but not the other FIA and USRRC cars.
