lol well there is two guys I work with that race NHRA, and they are putting in an order too, so I get to use their racer discount, and split shipping 3 ways! Plus I am getting a few more things too.

I have had to tighten up the bolts just one time so far. The stage 8's seem like a joke to me, however the breslins seem more practical.

Re: whats better, stage 8 or ARP header bolts?
I have 3/4" Stage 8s on both of my vehicle's headers, and never had a problem.
The Blazer has had them for 5 years now with Hooker Super Comp Shorties, and no leaks or backing out. I've never had to retighten them. The Z has had them for only a month or so with SLP shorties.
The trick with the Stage 8s is, when putting the locking washer on, make sure the bolt's head is positioned in such a way that if the bolt starts to back out, the washer hits a primary. If you do it this way, it is impossible for them to back out.
If they do back out on you, then the washer was installed with a gap between the flat part and the primary (if you were to spin the bolt left).

I used ARP SS studs with 12 pt nuts. They are a little clearance challenged, but gets rid of the possibility of having a bolt not go in or stripping/crossthreading holes. They get retorqued once and stay good & tight.

I'm sure they work great but i could only imagine what it would be like if you rounded out the center allen screw or it was ceased in there. That Bolt would never come out.

This will help the PITA LT1 header install bigtime. If I tried to a 12 point box wrench for the passenger side bolts I would probably burn the car to the ground out of pure frustration.

Im with ya on the frustration part! I have wanted to drive my car off a cliff several times, but now Im glad I didn't! I took your advice and ordered the stainless ones, 1 inch long, with the smaller 5/16" heads with 6 point heads. Thanks everyone for the help!
