Mystery SB Valve Covers & Rubber Gaskets

These were on the 340 in my 65 cuda when I got car in 2005. Ran for 2yrs. then removed and have sat in box since. Painted with black wrinkle,no dents but couple bolt hole repairs .They never leaked. No idea what yr. they are so you can have cheap. May even be two passenger units but they look cool on an orange SB and would as well on a red or blue one. PCV valve is new.
Thanks as always for the interest.
