Solid quality bolts for exhaust. Used on an LS3 crate engine.

These are high quality bolts. A great savings over the lesser grade Mr Gasket brand bolts.

Only been on 2 months but holding up just fine. Love the large head for better clamping force and better sealing.

Really nice header/exhaust manifold bolts. Put a dab of thread locker on before installing. Would buy again for sure

Good bolt kit but the description is wrong. They don't fit a LT1. Luckly I have a LS also so I used them on it but if your buying them for a LT1 your wasting your money

I used these new bolts for a new engine swap. Three of my exhaust bolts were broken off in the head. These new bolts threaded in fine and I put antiseize on them to prevent breaking in the future.

This is the third time ive come back, i always replace header bolts on an LS engine every gasket change. They have never broken, nor refused to come out.
