With the OD highway speed is not limited till you go beyond 4.10s and then is still double the legal limit anywhwere.

Most guys like 3.73s for daily drivers some even swear 4.10s are great for daily drivers.

I have tried 3.42s and 3.73s and when I put 20K a year on the car 3.42 was just right. Now it is more a toy and only sees 8-10K a year and 3.73s are fine even on 500 mile trips. Keep considering 4.10s.

To keep the ABS you need a custom reluctor, I can get you the email address for the guy if you want but it is not cheap, want to say around $100.

Headers you have a lot of choices ranging from cheap in every sense of the word headers meant for other cars that will take some fabrication to make work to stuff that can cost a little over $1000 but is of heavy construction and completely boltin with no fabrication or trip to the muffler shop necessary.

focuztech.com has a few choices and is good to buy from, great service.
Either ceramic coating or stainless should be considered as both insulate and protect the things near them from heat damage.
