I used these to replace the OEM bolts for my factory manifolds during an engine swap in my 2008 Chevy 2500HD, 6.0 liter gas LS engine. The factory bolts break often, especially the rear bolts. I used these hoping they won’t break. So far so good. But it’s only been a few thousand miles. But they do fit perfectly in factory manifolds.

Used these for my LS swapped c/10 with shorty headers. Went to tighten them after a few weeks of use and they were still tight. Very light and they look nice. I know it wasn’t needed but I wanted some bolts that looked a little better. Would buy again

I have these installed on my 5.3 liter gm engine. They look amazing paired with the headers. Bolts right up, and I feel much better since I use ARP for all my fasteners. Definitely will buy again if I get another project. Worth the money.
