Obviously the front and back hole fit on the alignment stud or bolt. What about the other end of each header? Does the tab just rest on the bolt or is some kind of up or down adjustment necessary so the ports line up?

Darren | | | | | Joined: Oct 2006 Posts: 1,847 'Bolter | | 'Bolter Joined: Oct 2006 Posts: 1,847 | did you grind the headers or the little tabs? The little tabs are a whole lot cheaper. | | | | | Joined: Sep 2010 Posts: 166 Shop Shark | | Shop Shark Joined: Sep 2010 Posts: 166 | I ground the little tabs and added a washer or two here and there. | | | | | Joined: Dec 2012 Posts: 163 'Bolter | | 'Bolter Joined: Dec 2012 Posts: 163 | I guess "tabs" was the wrong word. I am talking about the flanges. Mine rest on the bolts but the tops of the header are not flush with the tops of the head ports. I may have to adjust the headers up. It may not be that critical given the size of the ports. Any thoughts?
