Header questions....
My '96 TA got plugs at 115,000 miles just because I felt guilty. Didn't need them. Clean and gap was dead nuts. EFI, no oil burning & platinum plugs=long spark plug life. My old 454" Suburban got them at 120,000, wife's Lexus at 135,000. All same story. None ran any different. 100,000 is way safe.
A gear change will get you much more than headers, and no emissions issues.

Never owned a 2.73 geared F body. Personally, I would never buy one. 3.23 to 3.73 was about 1 mpg. Guessing maybe another mpg from 2.73? I just don't know. 3.42 is a good compromise for a 2.73 car. A couple of guys around here just bought whole rear ends from a stick car, exchange, from a salvage. All stick cars have 3.42 gears from the factory.
So 3.73 will be aftermarket? It's impossible in Russia to rebuilt the rear end
so buying the rear end in US i must be sure that it's good. I fully understand that i might get cracked one, but it will all depend on sellers honest. Will 3.43 dramatically differ from 2.73?

The limited slip 3.42 rear end from a manual trans F body, imho, would be your best deal. Your PCM would need programmed for the gear change also. Your speedo and shift points will be way off.
Good luck.

Verdad Gallardo Probably get you by, being where you are located. The older ones would not let you adjust the WOT shift points. Newer models might. They tend to hit the rev limiter on WOT gear changes if you made that big of a change years ago. A lot of the bad mouthing you hear about them here is not justified.
