CARS and the Buick Farm would be the first places I'd check.

Not all 300 and 225 engines had the french locks on the exhaust manifold bolts.  Sometime in 65 they switched to a different type of bolt that has a special locking washer captured behind the head.  I have seen some 65s that type, and some with the french locks.  I know my '66 300 has the type with the locking washer.

Range Rover used the Buick aluminum engine, may still, in the '80s and '90s. They used the same part for the exhaust manifoid bolt lock.
