...if I understand your question correctly its a toss up as to how you handle the problem. First where is your steering box? If its in the original location I'm not sure what will work. Some have moved the box our toward the tire about an inch to make exhaust headers work. I personally cannot say that a set of Ramhorns will work..... I have a set off a 283 I'm using but my steering box is outside the chassis....but if I remember correctly the ramhorms still hit the side of my original steering box unless you move it.
Ramhorn headers are available but pricey!! Whew!! Some say Corvette ramhorns?
I got lucky. An old friend gave me my set.
