Review on 🔩 Stage 8 - 8916 MOPAR Hemi V8 Header Bolt Kit - Complete Set of 17 Pieces - 8mm 1.25x25mm Bolts - 6 Point DHH by Ben Balas

2016 SRT 392 Challenger. I've used them before with mixed results. They work. Here's what you need to do to be successful. Once installed, do not install the locking tabs and e-clip immediately afterwards. Start the car and let it run long enough to reach normal operating temperature. Let cool and repeat. Check for exhaust leaks every time. If you hear a ticking noise from either motor then you have a leak. Tighten the screws after cooling. Repeat the process until all leaks are eliminated. After this process, attach the mounting tabs and clips. While the level 8 bolts can be tightened with an Allen key for further tightening with the tongue and clips, this is not possible as the Allen key will slip and snap off and you will then have to use an 11mm wrench. it is anyway. Also, the tabs are difficult to hold in place when attaching the clips, and some clips are difficult to remove and reattach. Follow these steps and save yourself the heartache. Another tip for Challenger/Charger owners: you never get a torque wrench for any of this. Dress carefully. You can snap off the head of the level 8 screw by tightening it firmly. Aluminum heads with stainless screws can be dangerous. So you tighten, check for leaks again, and then put on the tabs and clamps. This is a painful operation, like removing the cylinder head when you unscrew the bolts inside.
