12A vs 13B weight

My son is also wanting me to do this. He wants the SE, but knows there's no way I'll let him loose on the street with that monster 13B. It's just a bit too much for an inexperienced driver. He also knows the 12A isn't exactly a slouch, and is very capable of getting 20+ MPG, seeing as I have done so for more than 4.5 years.
I still have the old ST springs that came under the GS, and a set of 15s to fit the SE bolt pattern, so he could easily pursue his desire to run autocross with that car. The stock 14s have nearly new tires (under 500 miles) in spite of being 3-4 years old.
I'll prolly take the DLIDFIS off, and convert back to stock ignition on the SE. I just don't trust those GM HEI's enough for a daily driver. Even with the new mounting plate and best thermal goo, they run extremely hot.
I guess this swap is almost ready to take place. Kinda wish I had the funds to freshen up both engines during the swap, but that can be done a little later down the road.

My 12A header/presilencer uses 12mm studs. Does the SE header/presilencer use 10mm or 12mm? I've never got around to installing the presilencer on the 12A car, but the SE has the full street RB system, with an aftermarket muffler. I can always hook the 12A header to the SE presilencer even if it uses the 10mm studs. I could also use a different type presilencer under the other car, if the 13B header is only designed for 10mm studs, or just enlarge the holes in the flange......
I'll likely insist he change the rear muffler on the SE chassis. Being a bit older (and presumably wiser), I can get away with a bit louder exhaust than a teenager. Particularly when the SE looks rather shabby, due to being 1/2 covered with rattle can primer (previous owners doing). Cops love to pick on younger guys with shabby looking, loud cars, while ignoring older guys with better looking cars, even if it makes a lot more noise.
