340 driver's manifold

I also thought that at first but the holes don't looked like they were drilled, they looked like casting porosity holes....but I could be wrong and that's why I wrote the long detailed description. This way the buyer knows what they are getting. Besides those flaws the manifolds looks really nice!!!
PS - The shallow fissure in the surface that runs between the holes looked superficial after I had the manifold blasted and it was clean and bare. It didn't look like a crack, it looked like a shallow fissure in the surface (I've seen cracks before). I couldn't see why someone would drill holes to stop a crack that really isn't a crack??? That's why the holes didn't make any sense unless they were casting porosity holes.
