[jammin1]

i have set of bbk headers and want to know if anyone has used them in a cobra. i have done searches and they have not come up in any searches. this is going ona 5.0 engine in a MKII

I have them in my MKII with the 5.0 engine. They are a good choice.

I have them on my 5.0 in a mkII. One tube was a little close to the driver's side footbox. I pushed the footbox wall in about 1/4" and they fit fine.

MKII with a 5.0. I don't have the body on yet but they seem to fit just fine so far.

I had the BBK headers, fits OK on a 5.0, won't work with 351W, no clearance on the driver's side.

#2 cylinder tube has clearance issues with the 45 degree spark plug boots, so use spark plug wire set with 90 degree plug boots. On the Mark II, you will need to dimple the driver's footbox a little as cylinder #8 tube hits it.

There are Ford Motorsport headers that do fit better and dont' have above problems, but they are expensive (about $350).

If you are talking about unequal length then you may get some interference on the driver side on #8 cylinder where it just kisses the aluminum. I fixed this by inserting a piece of 3/4 chassis square tube lower down to spring the aluminum away from the exhaust.

I have the equal length bbk's and there is a slight interferance with the drivers side engine mount. I just dimpled the header a little. Comes close to the footbox, but does not touch.

Same headers here except I modified the motor mount (Energy Suspension brand) by cuttnig off the top of the clam-shell where the bolt goes through and welded it back together.

Also - I wrap my headers with DEI header tape and use 90 degree boots.

Don't think it will be an issue for you. I'm using BBK equal length headers in my MK III.

I modified my mounts the same as Randy, above, and was able to undertake a MASSIVE passenger footbox expansion with no interference. You can check out the pics in this thread:

BBKS won't work with GT40P heads. All but #2 plug clears.
