Thank you, I had originally forgotten about the BCU, I got two out of three so not bad right? lol

I'm in New York State, so a "check engine" light during annual inspection is a concern. The donor motor is in good shape, with a bit over 100,000 miles. The blown motor has never been apart, as far as I can tell, so I will take the heads off that one, and at least check for cracks and deck flatness. I'll see what they look like and maybe go through and do seals while they're off. I appreciate the consideration on swapping the boxes, but I think for future serviceability and parts identification, I'll go with maintaining the stock 2002 SAI configuration, as crappy as it is.
Thanks to all for your solid input.
