Gonna need headers on my 89 Burb when I drop the 383 in. Thinking Hedman Elites will be best. Nice thick flanges to prevent warping cause this thing will see plenty of highway time, and coating should keep them nice for a good amount of time. Anyone have experience with these things? $260 from Summit is more than I like(never paid more than $99 for headers, but hey quality usually costs a little more.
