I live 5 minutes away from the JY, would it hurt to grab the parts off a junker gtp ssei or Riviera?
I don't really see a question here that hasn't been answered in the threads you speak of.
Yes, go to the junkyard. I love the junkyard, got a longblock L67 and 2004 CompG trans for $250 together.
Who wants to pay more for less? Pay less for more, as long as you can tell the junk aside from the spare parts.
The factory exhaust on the heads are manifolds, I would never M90 an L36/26 without headers/separate cylinder primaries.

The mileage on your car shouldn't be a huge factor if it is put together correctly and the pistons are completely intact as it sits.
