Headers for a 64with a small block

Ok, I have been searching high and low for headers for a 64" with a small block. I bought a set ob BBK for a fox mustang and they fit great except for the pass side hit the a-arm bracket whick could have been trimmed. the driver side would have fit great except it hit the drag link. another 1/2" and it would have worked. So I took them back and bought a set of hooker comps for a 65-73 mustang with a 289-302. Wa-lah after some very mild clearancing on the engine frame mounts with a hammer(very mild) they fit like a glove! Only one problem because they are typical headers that turn in the miss the hump in the crosss member and I can't get a collector to bolt on. So I am now going to fab up a new cross member!!

That's good to know for those that would want headers!

Headers from a mid 80s - early 90s Ford truck will fit.

Are the headers from the 80's truck long tube or short tube? I already had shorty headers but I am after long tubes.
