I replaced the radiator today along with new coolant and flushed the system. The old radiator was full of sludge and crap but the car runs great now and the temps are right where they should be. Problem Solved! Hope everyone else can find success.
Don't forget the compression height. That's the distance from the wrist pin to the piston face. That changed along with rod length. You generally want to keep pistons and rods together as a set since Subaru selected the rod length and compression height to match the chamber volume and HG thickness to achieve a specific compression ratio and quench.

I marked the amount of rotation on the old socket with a welding marker, then trimmed the rotation stop tab off the new socket and marked it where it fits in. It will twist in now and the marks line up. Now I just need to wire it up .
