BBK one-piece flange or MAC individual flange long tube headers.

[Fox Body]

I ran into some money and was considering swapping my headers for some 1 3/4" long tubes. I have 1 5/8" shorty MAC headers that are individually flanged. The ones from BBK are one piece flange headers and specify '79-'93 351w.

So these are my concerns/questions:

1) I don't know if it's such a good idea in the long run to have individual flange long tubes. (concerned about installation/warping).

2) I'm not really sure at this point if long tubes would help or hurt the car's performance. (Large amounts of exhaust air flow isn't ALWAYS better).

3) HAS ANYONE USED EITHER MAC OR BBK LONG TUBES? LIKES/DISLIKES?

4) What is the diff. b/t full length headers and long tube headers?

Thanks for your input.
