New EQ Head port misalignment?

I’ve only ever had a few used Magnum heads in my shop, and they had come off trucks that had been used as trucks.
Exhaust seats really pounded out and sunk, big wide cracks running across and down into both bowls.

At the time we would buy remanned castings(welded, new guides, valve job, surfaced) and reuse the original parts from the customers heads(after cleaning everything and refacing the valves).
