Unknown cylinder head info needed if you can

Bought a set of heads. They where said to be Trickflow 23 degree heads. I cant find a part number where trickflow normally stamps it.
All I could find on the ends of the heads where the numbers GO2278-1 and GO2274-1 its either GO or G0 <zero.

No other stampings anywhere but for a small A009 and A012 Anyinfo would be nice thanks
