When properly installed Stage 8 header bolts have always done what they're supposed to. No header gasket leaks! Excellent product, reasonable price, and fast shipping.

Overpriced for what they are. I had to modify the locking tabs on most of the bolts to fit on the headers of my 93 Chevy 350, one of the most common engines out there. Overall I at least expected the tabs to work without modification because that is what would set them apart from any regular header bolts
