I have several exhaust manifolds. the first set is:
3909879 & 3868874.
I understand the 879 may be a coipo manifold? is this worth anything?

The second set is 3856306 & 38792307.

It is strange because the 306 is dated l2 84.
Does this mean it was cast in 64? Could this valuable since big blocks technically came about in 65?

Thanks,
