I put some hooker super comp headers on my truck....
95 250 351w
I am currently on my 3rd set up gaskets for the dang things.
The bolts absolutly will not stay tight. Ive tried blue lock tite, ive tried red lock tite. Im so tired of dealing with this crap. One of my biggest pet peeves is exhaust leaks and this things is horrible. I get it all sealed up and it runs nice for a few days then it starts again, i get that side fixed all is good for a few days then the other side starts... Im to the point now that i want to pull the whole motor. and weld that damn headers to the heads. Am i doing something wrong here, or whats the fix... If its just the nature of the beast, then im layin a bead around it, and if that dont fix it, im gunna blow it up. I am so tired of it. Everytime it starts i want to scream and lite my truck on fire.
I don't know what gaskets you are using but I would use Ultra seals from Mr Gasket. Use antiseize on the bolts & check them everyday for at least a week or until you don't find them loose. Make sure the heads are clean & free of old gasket material. If that doesnt work, cut the flange between cylinders to make sure each port is tight to the head.
Im not worried about the bolt's seizeing, hell if they would seize that would be great. It would stop them from backing out all the time. Ill see what else comes up, but ill keep that all in mind. Thanks for the info and idea's

Antiseize is use to lubricate the threads to ensure an accurate torque on the bolts & believe it or not will work to keep the bolts from backing out.
I know it has one hanger, fairly sure it has 2.
Not 100 % on that one.
Right.. if the headers are carrying most of the weight of the exhaust system the bolts will never stay tight.
You may also want to check the condition of your engine mounts, if they are sacked or no longer attached to the frame the motor will move around more than it should.
I vote that you use the twisted-wire technique used to keep aircraft blots tight on essential parts. (IE: the prop) Not sure what the technical name for that procedure is.
I have the same problem with my long tubes. I have true duals, X pipe and two mufflers. The exhaust is very stable, but has enough play in it. I went with Socket Head Cap Screws so I can get a better toruqe on them. Maybe try red rtv...hi temp stuff
