small block exhaust manifold cast #?

I am getting ready to post to sell a set of exhaust manifolds I had ready to bolt in 65 Valiant I sold. Identical to the 273 manifolds originally on car- Confuse about #s when I looked up on various sources.
Pass side is #2465769 date 4-12-66
Driver side is #24658(or6?)4(or5?)7

date? 8134

Anyone know for sure what fit?
Thanks
