Chevy BB heads #10101140

I have a pair of large oval port heads with casting #10101140. I've tried to find some information about these heads, valve size, chamber size etc. but with no luck.
They are GenV closed chamber and they were for the 366T and 427T.
Anyone has some more info??
Are they something worth to use for a 454??
