Review on Stage 8912 Locking Header Bolts by Tim Surridge

Not installed yet there will be some spacing issues with the headers I have (short headers for LT1 to Jeep conversion). Some clearance is required between the header pipes and the bolt holes, and with wrap-around headers like mine you don't have much clearance to work with. With some modifications I think they can be made to work (sanding or blocking out the "tear" pieces). If you are very close to the holes it might be better to use a safety wire. But the product itself looks top notch if you have the space.
