Glad we can help Durangod..

AS for the other two loose nuts (Hydra/Dragon) your misconception of grade 8 header bolts is wrong. They are always recomended with aftermarket headers and are the choice of 20x manufacturers..

 

You'll get it and your welcome!....

 

Blah, blah, blah.......


If you are going to use grade 8 they need to be heat treated. Thing is if you install grade 8 they are prone to vibration breaking. Grade 8 SS is softer like grade 5 regular but.....IMHO.....should only be used in race ready. With regular bolts they oxidise to help the bolts from backing out.


But like I said........ IMHO
