Help needed on 318 buildup/THERMOQUAD

[e-tek]

I've been finalizing my 318 for the chilly Challenger and was hoping (OK Knowing!) I could get a bit of help...Is there a set of headers that fit best? Summit has best deals and offers several manufacture choices. The car was running/driving prior - should I do anything to the tranny? I don't want to pay for a complete rebuild, but maybe there's a low-buck check/cleanup I should do?
The carb - A 74 (I think) Thermobog - I rebuilt it complete and was just putting all the linkages back together. Any tips/tricks or things to wathc for here? Seems a right complicated thingy!
Of course any ideas, tips, comments are welcomed. I'll post this pic of it on my test stand, in case you want to zoom-in on the carb. Cheers.

The Thermoquad is a great carburetor, but must be understood to be properly tuned. There is a book about the Carter carbs that will help you here, called Super Tuning and Modifying Carter Carburetors, from S-A Design (SA11). Everything I didn't already know about Carter carbs, it taught me. Air valve tension, metering rod hanger spring height, and a myriad of other specs and adjustments are covered in depth. If you need some specific advice on driveability problems, ask here, and somebody will be able to help. It looks great.

the Best headers are the TTi ,  Hookeralso make a specific header that stays above the steering linkage , I have posted the # here before do a search , if you cannot locate it I will look it up again , DO Not use any header that drops below the steering link , it will be smashed flat in a week

Chall Looks Great BTW

Super - thanks -I'll get that book - I'm sure I'll make use of it. After stripping it It looks like every linkage and pump needs to be measured and reset.
Chryco - I'm leaning to the Hookers, just becuase the tti's are so expensive (in canada anyways). Thanks for the tip on low-hangers, appreciated.
