They should work, though I was unable to use two of the locking washers due to the header's design.

It really works

5/5

These are the best header bolts you can buy, and if the lock washers don't fit, it's because you need to shave them down to fit in between some of your header tube. All I did was take a drimmel and grind the flat side down until it fit, and it was as easy as that.

They are extremely effective

Headers will love it

5/5

These work best on any headers if you tighten them down every time you go for a drive before installing the locking devices, which I do until they don't tighten any more. That's the gasket you're working on. I did it a total of ten times/drives on various days. The header will no longer leak as a result of this. The fasteners do exactly what they say they will do and do not loosen!.

It's possible that the hardest-to-fit location will need to be ground down a little

5/5

These are the best in my opinion, not because they are the simplest, but because they are done correctly the first time.

excellent price-to-quality ratio They work great, and despite being torqued once during installation, they haven't backed out after many heat cycles and heavy use

5/5

Because of brackets on the passenger side, I couldn't use two, but it wasn't a deal breaker.

They'll have to replace the two that aren't there

3/5

I received my stage 8 bolts, which are of good quality. The box stated that there were 12 bolts in it, but there were only ten, and the box had been opened.
