3/4 inch header bolts were too short on SBF.The headers and thick gasket required a longer bolt. 1 inch worked perfect. Fast shipping!!

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.

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

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.

better than most locking header bolts ive used. Wasnt able to use the locks on a header bolt though.... this is because the half moom washer doesnt always hit in right spot. all in all i like them
