Default 63 Super Duty Heads 9771980 Crane prepared and stamped

I have a pair of 63 9771980 SD heads that were prepared and stamped with a # from Crane Cams. Does anyone have any info or ever heard of them? Any help would be helpful. Also Have a M. Thompson Duel Quad Manifold 54299 Alum. 63 Vintage
