First off, the 7/16" hex heads are too big for tight headers, so I couldn't even get a wrench on 4 of the bolts. One of the remaining bolts that I did get tightened, bent! Decent design, poor quality.

I was having issues with the header bolts that came with my Pacesetter headers. I went thru 3 sets of gaskets before buying this product. Once installed and tightned no more issues. Rechecked after a few heat cycles, and still tight. Easy to remove when needed, and just retighten.

I didn't use them on "headers", I used them on an intake manifold, mwaahaahaaa! But they haven't come loose yet! Only made in USA gets 5 stars though.
