What about those Heddman torque step headers? They go from 1 1/2" into 1 5/8", have a firecone where the equal length tubes merge, ceramic coated...
If I were to buy some street headers, that would be my choice for a nearly stock, mildly modified setup. Anyone on the list have them or know anyone who runs them? I ran Dynomax equal length shorty's before getting long tubes, and I did not notice any seat-of-the-pants improvement when installed with stock, unported heads, etc. They were there when I was ready for them later down the road when my dad hogged out my E7's, and I bought a nitrous kit and mild cam/springs...
Back to your bolt on issue, my opinion has already been stated as far as the list of mods go... I don't believe you would have any problems running the pulleys as long as you run the overdrive pulley on the alternator, even with an elec. fan setup.
And if you plan on a t.b. and MAF without ever changing the intake or even carving around on it; well, that's up to you and only you -- it's your car afterall...
As far as your fuel system goes, a bigger in-tank pump, a clean filter, and an adj. pressure reg. are good mods... But if you plan on a MAF and t.b., might as well upgrade to some 24lb injectors.
The list of mods, and what order to do them in is ENDLESS!!
That is exactly what makes it so much fun
