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..

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
