Fit as in hit the firewall? If so get shorter dog bones to re-align the motor I suppose. Watch the U-Bend on the Speed Daddy brand ones, may hit the ground. easy fix just reweld it
I have shorter dog bones and anti pogo washers that haven't been installed.
I saw a video of the Speed Daddy headers on a 3800 but not sure what car.
He had issues with the front manifold right up against the radiator fan.
The headers can run close to the fans, but I never had an issue on my car when I had them.
1) Buy headers
2) Start install
3) Check clearance with shorter bones
4) Check again with longer Bones
5) Choose the better option
6) Finish install

I was lowered 1.5in overall and never smacked the downpipe on the ground with speed daddys in the 3-4 years I had them.
Shorter dog bones don't do anything to help you there. Cut and re-weld the downpipe or run it as is.
On 97-03's it will likely hit the fan shroud with shorter dog bones anyway, they are really close even with the stock ones.
ZZP has a fan spacer kit that moves the fan closer to the radiator for more clearance with headers. It looks like three screws and three washers.
