Anyone running Kooks long tube headers?

[69mach1build 24]

I am looking for 1-7/8in primaries and 3" primaries.  AFR recommended these kooks headers for my AFR 220s but I'm concerned about their fitment.  I'm running a stock manual steering setup and TKO600.

Just from looking at the pictures, I can tell you right now those aren't going to fit unless you have eliminated the shock towers. With your needs, FPA is probably the only luck you'll have with 1-7/8" primaries with the AFR bolt spacing.

The application for those headers specify 1979-1993 Mustangs.  I doubt they will fit a 1969 Mustang.

What about 1 3/4" primaries? Any long tube that fit 69s?

With the AFR bolt spacing your options are pretty limited. Even 1-3/4" primaries might bottleneck the heads if the headers have standard spacing. Do post up any information you come across for future reference though.

I called and talked to FPA, sounds like that is currently my best option. They quoted around $700 for 1 3/4" primaries.

FPA = Great 1 3/4 Headers with wide bolt pattern.

Went with JBA, but I have no shock towers.
