as far as quality and bang for the buck i woudl say yes. we sell them for 899.00 i think if you look at nrgular non coated headers and then add coating. i think your way better off and they are stainless
some of the issues we have seen is in the actual frame stands, there are some variances we just did a nova and tried 2 different frame stands to find the rigth ones we ended up using classic performance # E304 these list for a BB 69 dont know if this will help but they worked??
I used ARH headers and they are really good quality. Plenty of room for rack & pinion or stock steering. They have so much ground clearance. They're not even close to sticking below the subframe, and they fit great with DSE mounts. http://www.americanracingheaders.com...ebird_LS1.html
They're a little more expensive but if you call they may be able to get you a deal
