8912 Locking Header Bolt Kit with 3/4" Bolts

Have not installed yet, will have some clearance issues with the headers I have (shorty headers for an LT1 into a Jeep conversion). You need a certain amount of space between the header tubes and the bolt holes, and with wrapped headers like mine you don't have much clearance to work with. With some modification, I think these may be made to work (grinding downt eh locking 'teardrop' pieces). If you are super tight to the holes, you may be better served using safety wire instead. But, the product themselves, if you have room, looks top notch.

Excellent
