ford racing v10 headers????
Has anyone heard about them, are they good? The application guide says for model year 2004, mines a 2002, is there a difference? $379 seems like a good price considering their from Ford.

The problem with "well designed" and "equal length runners" is the length of the runner, and the diameter. Both determine where the header helps the most in scavenging exhaust from the cylinders. Banks is expensive, but seems to do the most in that department for TOWING, at least that's what most people think.

I have pics of my Thorley headers in my gallery. They are close to equal length but not exact. I've seen equal length shorties for mustangs and they are all twisted up like a pretzel.

The V10 is an even-firing engine. First, it fires each cylinder exactly 72 degrees apart. Which makes it the definition of "even fire". (A little history: The Buick V6 that is known as an "odd fire" actually used what looked like an 8-cylinder distributor cap with two posts missing. It actually had a huge gap in two places)
Then, it fires from bank 1, and then bank 2, and back to bank 1.

So, with the V10, it's VERY possible to get an equal length header that actually does it the "right way".
On the Ford FE series, like the 360 and 390's in many many pickup trucks out here, it actually fires two cylinders in one bank one right after the other. Making truly "scavanging" headers almost impossible to make unless you cross over from one bank to the other.

The 4.6 and the 5.4 fire bank-to-bank. The FE I used as an example is still an EVEN-FIRE engine. It just doesn't fire bank-to-bank, it has certain cylinders in ONE bank firing right after each other.
