Prepare yourself to redo your header bolts
After losing half of my arp bolts, I swapped these in.. After I stopped swearing, I'm happy to have done it.I do wish they were 12 point, with the Allen drive, but I guess you can't have everything.

Great Product
These are the answer to leaking headers. Use a good gasket and these, torque the once, lock and forget about it. Don’t have to touch them again

Great for Sbf engines with headers
Worked great on my SBF TRI-Y headers on AFR185 heads no real issues.

Get the right bolts (these!). Get the right gaskets. And your new headers won't leak! Something that's extremely useful during install with these is that you can use the hex pattern on the outside of the bolt head with you socket/wrench....OR you can use the hex pattern inside the head with an allen key. It just gives you another option when your shorties limit your space.

style matters
bolts are great, if after 3 times calling you get correct ones ..the person on phone don't know parts or how they work some are round locks others are tear drop ,not all motors are same spacing on bolts so fit matters, after 3 time returning and still getting wrong ones went to local parts house ,spent more but got correct part number I had ordered 1 time ,NOT THE BOLT FAULT... there a great item..will buy more from local.....
