Header Bolts

[truckster]

Does anyone have any recommendations for header bolts that are particularly good at holding on?

Most brands are no better than others. I've always used off the shelf header bolts from the local auto supplier. They just need to be re-torqued 2 or 3 times of hot to cold cycling.

Be sure to use anti-seize on header bolts.

I wasted $150 on other bolt kits, before I tried the Stage 8's!

They are by far the best I have used.

Totally Stainless sells something called a Total-Loc header bolt that's supposed to be really good, but they're kinda pricy.

if you use stage "8" header bolts with locks you'll never use anything else. They certainly are much much better. John

I have found that on my big block truck you can use grade 8 bolts with lockwashers, but on small blocks I have used regular header bolts and drilled and safety wired them with no problems.

We sell Stage 8 header bolts- same part number $39.95 We can usually beat Jeg's or Summit prices on everything

im using the ones from autozone the one that had a head for a socket or allen wrench or whatever its called and they worked great

[bigsnookmaster]

I'm not exactly sure of the name, but the ones I use are 12 point stainless with an allen set screw in the middle, you snug your bolt, then tighten the set screw. They work great, and cost about 50 bucks, so you don't want to lose one. Good luck

I bought some off the shelf ones at a local hi po store that had 3/8" heads instead of 7/16. I put some loc-tite on them and they never came loose... And before you say it, I had no problem cracking them loose when the &%$# gasket flew south on me...

In the last 15 or 20 years i've had zero grasket failure, or never had to retourque them using stage "8" header bolts. john

Simple remedy is a hack saw. Get the cheapo header bolts, tighten them and forget about them. Oh and get ya a set of manifold gaskets for about 7 bucks. No problems going on 20 years.

i just use whatever comes with the headers mostly or buy stainless allen head bolts

i do routine maintenence like when i change oil i check and tighten header bolts clean and lube linkages and other moving parts check hoses etc
