Felpro 1406s. Cheap and reliable. I've never used anything else because I've never had these leak on 3 different headers.

^^^
Only time I've ever had one blow out is from a Stage 8 locking bolt failure on #2 primary after it had backed out multiple times.

X3. I have only had one go out because I had 2 bolts back out.

Tips to help: I use Totally Stainless Header Bolts because they come with a 5/16 head so I can get to them easier with a wrench or socket and they have locking washers so they seem to hold better, but I tighten the HELL out of them when I install. Once done, run the car at operating temp for a day, then re-tighten ALL of the bolts! Do that 2 or 3 times and you should never have a problem! I havent since I started doing that!

I use MLS like the factory uses. They wont ever fail even if a bolt backs out.
