Wheels/ head info!!!!!!!!!!!!!!!!!!!!!!!!!
Ok i've got a lot of mixed answers to these questions but no one has ever given me a difinitive answer.
1) will Srt-4 Rims and tires fit a 1st gen neon (bolt pattern is the same and the offset isn't off by much)
2) will the 2.4 cylinder heads from other dodge cars (stratus,srt-4, etc.) bolt up and work and on a 1st gen dohc motor (i'm looking to add more torque) and if they do what ecu would it to run it?

RE: Wheels/ head info!!!!!!!!!!!!!!!!!!!!!!!!!
The SRT-4 stock wheels are 5x100, 17x6", 45mm offset w/ 205/50R17's (8.1" wide x 25.1" tall); and the SRT-4 ACR wheels are 5x100, 16x7", 40mm offset w/ 225/45R16's (8.9" wide x 24" tall).
The 1st gen Neon will only tolerate about 6" of total backspacing (wheel and tire, usually it's the tire that rubs, not the wheel).
The stock SRT-4 wheel/tire combo has 5.8" of backspacing, so there's a very slight chance of rubbing, so a generic 3mm spacer might be a good idea (don't go any bigger than a 5mm spacer without longer wheel studs and a properly designed $pacer). Keep in mind the tires are also a good half inch taller than stock and becuase of the additional width will probably rub on the bottom of the spring perch in the rear (space should help with that as well).
The stock SRT-4 ACR wheel/tire combo has a little over 6" of backspacing. I wouldn't bother with a spacer, just go with a set of rear trailing arms from www.neongoodies.com specifically designed for wider tires. The height won't be an issue.
The heads used on the 2.4L cloud cars and minivans is the same casting number as the Neon DOHC head. The SRT-4 and newer PT Cruiser setups are slightly different, and I haven't kept up with the changes to prvide details, only that it is NOT a direct swap.
The extra torque the 2.4L's have is from the extra displacement. You'll actually lose power with the "new" head on your 2.0L because it has a weaker intake cam than the Neon does. If you want the extra torque, swap in the entire 2.4L engine. There's more to it that that, of course... but it's still a fairly straightforward swap. Best when used with a turbo.
Best of luck!
