Aluminum Timing Cover Damage

I've had to take more than one SB timing cover in for a resurfacing. I've had plenty of leaks from them.
On my most recent (sold) Dakota I had reciepts from where the PO had had the water pump done at 86k.
At 92k, it leaked right there. He paid the same idiots AGAIN for it to be taken apart a 2nd time to replace the timing cover gasket.
I got it with 105k on it, by 120k, I had it apart for the same leak, right under The alternator, and the timing cover looked like the one in the post above.
I had another one here that had suffered the same fate that I'd replaced previous on another engine, I took it to the machine shop and had them mill off enough to get rid of the pits, I think it took like 15-thou he had said at the time.
EQ, yeah the company that used to sell a dang good magnum head replacement also sells reman parts, among them that they sell is a reman timing cover for these engines. Know how they " reman," them? By putting it in a mill and shaving off enough to get rid of the pits. I've been working on and owning mopars since the mid 80s and until about 7-8 years ago never saw one pitted up on the gasket surface like that.
In those 7-8 years I'd guess I've had to fix 1 of them a year for that condition
