I thought these breslens looked a bit much.....I’ve used the proform wedge lock, as well as the mr gasket headlock bolts, and I prefer the mr gasket ones since they have an Allen key hole along with the 6 point hex.
Both work well and have serrations to dig into the flange though.
Idk, I’ve never used those. I like to have 6 point flats on the outside so I can get an open end wrench on tight ones. I stay away from 12pt.I thought these breslens looked a bit much.....
So nobody using the bolts that come with your headers??
The last time I used headers on a car was on my Z28 in the late 70's,,,, Curious on whats new in products..I’ve used bolts that came with headers and been just fine. Most important thing is you run through the torque sequence several times until they all take the same amount and don’t budge. Then tighten again after a couple heat cycles.
If the flange is square and you use a mls style gasket, the bolt style doesn’t matter.
I’ve had good luck with those. The Allen key hole is a lifesaver.I always recommend locking header bolts as they tend to work themselves loose over time. I've used Stage 8 before with good results but this time I'm gonna try these and see how they work out......
