I'm not gonna jump on the thread locker or safety wire wagon right off, I have a feeling there's some amount of heat cycle expansion / relaxation of the gaskets... you'll want to snug down new gaskets at some point early on in their life maybe a couple times or more?
 
on those hard to reach bolts even the Stage 8 C-clips would be a bear to do a snugger with a BBF
 
I could do a snugger with a 3/8 combo wrench in about 6 minutes on the 351C 
 
has anyone ever gotten a set of header gaskets to last more than a couple months?
 
does anyone think it's possible to use a high rate spring loaded bolt set-up, or would the heat kill the springs?
 
bellevilles ?

The set I posted pics of were about 3 years old, no leaks, but only about 5-6K miles. Just saw on Powerblock today that Mr. Gasket makes a header gasket using dead-soft aluminum, looked OK just didn't give a lot of info on them.

Yeah, It's a Hybrid...It burns gas and tires.

ARP 400-1105 and ARP 400-1106 are six point header bolts (0.750 and 0.875 lengths) that are pre-drilled for safety wire (also known as lock wire). They do not have the recessed hex head like some of the others, but since I can get a pair on now (non pre-drilled ARP header bolts) this should work. I can see putting the safety wire on in some of the locations being possibly problematic because of the space limitations. Otherwise a reasonable solution.

This is another option to keep the bolts tight, just not sure of the quality:

Weird. I've always run the Hookers. Never had a problem. They seal & stay tight when u us good reusable gaskets. I can get all my bolts in & out & change gaskets in the car no problem. And that's on both race cars. Sorry, just lucky I guess.

ULTRA COPPER on ALL exhaust gaskets I have installed in the last 20 years!!
NEVER put an exhaust gasket on without it! You could also use a touch of ULTRA BLUE around the ports on the flange itself to ensure it fills any voids THEN with the Ultra Copper and a good gasket... no issues.
 
As for header bolts... I too have never had any issues with just bolts and lock washers.

Just an afterthought, are you using the Ford mounts, or Crites mounts. The Crites mounts drop the motor about an inch to the frame/crossmember. One of the primarys on the driver's side is pretty much resting on the crossmember. Which would make it ever more of a pain to get in. It seems the headers have clearanced themselves in a couple spots. For what it's worth, I used those Remflex gaskets, with ARP header bolts, and haven't had an issue. I know they leak a tiny bit, but it's no worse than what it was the day I bolted the headers back up. No Locktite, and no Permatex for me.
