I'm running those with a stock clip and CBR rack and pinion and they fit easily.I ordered Dougs headers from Summit. I could not be happier! They hug the block perfectly and the quality seems very good. Now, the price....
The reason for Summit as they will take them back if you can't make them work (as long as you have not installed anyway) as I was worried they would not fit the way I wanted. Doug's Headers D317-B Doug's Headers | Summit Racing
The one on the left is a typical set - you can see the indent for the steering shaft required.. The one on the right is the Dougs Header.
You can see how much clearance I have now.
