Questions & Answers

I have a 4 and am wondering if these will fit. What do you think of the 6l vortex?

The thread for the Chevy. The program can be run on any platform. There are a few in my Vortex V-

On my Chevy 350, I have Edelbrock performer rpm heads with a 60899 thread pattern. Will this bolt fit?

I used them on a Chevy 350, so they should be fine

This item will fit a 2011 iPhone What's the difference between 3 and 4 ?

So I think I used it on a 1994 Chevrolet with a 350 that I had aftermarket shorty heads installed on.

How does this fit a vortec 350 from a 97 Tahoe with BBK shorties?

These were used on a 94 Chevy with a 350 and shorty headers and worked perfectly.

Selected User Reviews For Stage 8 8911 3/4" Locking Header Bolt Kit for GM Small Block

The work is okay, the appearance is good, but the softness is not great
3/5

They are a cool design they work okay and look nice the metal is softer than I'd like though (they are not Grade 8 like I wanted), and the Allen-Bradley hub drives seem to do the job. There will be a rounding of the center of the wrench socket The way out- The Allen wrench head spins when it is tight, in places where a standard socket cannot be used, and where a standard open-end wrench won't work either With a wrench end, you will achieve the same result- rounded corners on the bolt. Flat washers can also be adapted a bit to fit in certain.

The header bolts were installed ONE time
5/5

Great locks, but I had to modify three or four of them in order to make these work I don't think it's worth the effort to not have these returned.
