63 F85 Cutlass

I just recently aquired a pair of finned aluminum valve covers for my 215, they have no name on them, and the only casting on the underside is F85. I was wondering if anyone knew of who has made valve covers for 215's other than Offenhauser and Edelbrock? I was thinking possibly micky tompson, i know he's built 215's before, mainly buicks which were different heads, but who knows. If you have any ideas let me know, i'll post pics soon
