I dunno about that, I think a lot of the higher dollar pro-touring builds are probably in a power range that a larger diameter header would be beneficial and most of those guys aren't going to run manual steering.
Now granted, a lot of those builds are using modern engines too.
I dunno about that either. The Borgeson power steering box isn't significantly larger than a manual steering box for these cars.
Now, getting a "real" header to fit around a factory power steering box is a different story.
your talking about the .01 % of builds I mentioned. Not many high dollar builds these days are LA oriented. And Doug’s and TTI’s will cover 99% of the few of those that exist( and have power steering.
Way more high buck gen2/ gen 3 type stuff these days getting built.
Or, guys are doing turbo stuff which takes this header talk off the table
And what headers have you used on a small block? Because if the tubes are under the steering link they have less clearance than Doug's or TTI long tubes.
