Using hedman on my 360. They are fairly cheap and do not hit any thing, BUT...they do have two drawbacks.
First off, they hang low under steering linkage, so I always have to lookout for anything in the road. I had a set a few years ago that I bent on a friend's gravel driveway.
Secondly, it is very hard to get to the rear 2 spark plugs on the driver's side without taking the header off.
Other than that, they work great for my combination.
