He asked for cheap, but also asked for not going under the steering linkage. On an E-body that combination starts with the Dougs mentioned above. Truck and Jeep headers don't add much to the conversation because even the cheap ones route with plenty of clearance to other components and ground clearance usually isn't an issue. On an E-body with the stance of the two in OPs post, cheap headers will be low to the ground. Unless you drive very careful the drivers side will end up with dents eventually.

I've run cheap headman and cheap summit about 10 years apart. Summits were thicker flanged and seemed better built, but with the gap in years headman may have improved theirs too. Look up the installation instructions, Jegs is better about a convienient link than summit. I'd bet money the cheapies still wrap under the center link especially if it lists the same application as fitting a bodies also.
