Not a easy fit had to modify... I repeat does not clear steering Box... I had to put so many dents on the headers now I'm thinking what's the point...

Check the bolt holes!!!
I was initially surprised at the quality of construction of these headers. So much so that I had them blasted and I painted them with high temp paint form VHT. When I tried to install them on my car I couldn't get them to line up with the studs. Luckily I had an extra cylinder head laying around. When I checked the header against the head i was shocked to see the bolt holes didn't line up! It took me an hour of drilling and filing to get it to line up with the studs. The overall quality of the headers is good but the bolt holes being off is kind of ridiculous.
