Need an opinion or two here on what to do. I recently bought a 440 with these heads. I wanted to freshen up the bearings and go with a smaller cam, so I disassembled it to find the Eddy heads have all these pock marks on them.

There is damage to every cylinder on each head. It appears it happened before and was rebuilt with new pistons, etc. because there is no damage at all to any piston or wall- just the heads.

Anyway, look at these pics and tell me if there is any hope of repairing the pock marks to the aluminum. Pretty crazy that ALL the cylinders have the damage. Or is this in the castings? Is it a concern at all? Hot spots, etc.?
