Is there room to route the spark plug wires under the headers? Header look like they hug the engine and space would be limited.

Small update...

I got my headers yesterday and they are bad a$$. Will post pics and of course start a build thread soon. Stay tuned. But, for others that are considering Ultimate Headers, I'm completely, 100% satisfied with the entire transaction. That's rare in today's business world. Jim was great from start to finish. They answered all of my questions, called me back when I called them and left a message, emailed me pics and PDF files for measurements, etc. The whole 9 yards!! I highly recommend them.
