They aren't necessary. Some people want the added security of a locking bolt, and are willing to pay for it. Some feel it's a complete waste of money. It's not like your headers are going to fall off if you don't use a locking bolt. It's like choosing between stainless headers and mild steel. For me, anything less than stainless wasn't a consideration and I was willing to pay the difference in price. If I had not found some Breslin bolts, I would have used ARP's.

Reminds me it really depends on why type of header used that can decide what bolt to go with (either Stage 8 or ARP at least). I tried to use Stage 8's on my Hooker LT's and there was no chance in hell being able to use the locks and it was impossible to fully tighten the front bolt and was also impossible to use a bolt on the back of the #3 primary between that and the #5 primary. These were 7/16 and were just not worth the trouble. Perhaps they work better for certain headers more than others.

I know someone that used Stage 8's with Kooks. He left off a few of the locks because he couldn't get them on. That kind of defeats the purpose, imo. If you want a locking bolt, the split lock design is much better, imo.
ya thats exactly the thing i mean they are really expensive for bolts i dont really want to spend 60$ on darn bolts you know ?
b/c my stock ones were not locking and WOW were those a PITA they were NEVER coming out on their own you know?
i wonder if the aluminum heads has anything to do with it.

Bolts I have used the Breslin's in the past. Pretty easy install. The Stage 8 and similar are a pain. You have to grind on the lock tabs like 69gto96z said to get them to fit certain tubes. Jegs and Summit have both discontinued this brand. Percy's are available. Just ordered mine but they are back order for about a month. Hope this helps.

because Percy bought out the bolts, so they are
now under the Percy name. I have Kooks on the
way and have been told that the Stage 8 would
have to be ground some. The Percy's wont be
in stock at Jegs or Summit until about April,
so will have to wait.
Spending money on Percy bolts is a drop in the
bucket when you consider the cost of Kooks/cats/y ...
... it's piece of mind.
they are not gonna come loose, i got the 12 point 5/16 bolts stainless through ARP and they dont even loosen up. the time spent putting locks on you could check them 18 times...
