Exhaust manifold question

[blown motor]

These came with my charger, 440 engine. What exactly are they, standard or high performance? What are they worth?

They look like the standard manifolds.

You need to find someone doing a ground-up on a sea body by the look of it.

The 107 casting is a 65-69 left C body LP (low performance) big block exhaust manifold. The 464 casting is a right side 66-69 B and C body LP big block exhaust manifold. Not much value for either exhaust manifold. Hope this helps.
