Mopar 440 Big block header bolts.

[1967coronet]

This napa sealer is also a anti seize.
It's for hydraulics and steam fittings.
It is a lead base sealer.
Never had a header bolt or stud leak using this.

There's many different Permatex products. This one has been around longer than me and has never failed the many jobs I've used it on.

The Tri-Y's are great but I don't know if anyone makes them anymore that Schumacher is out of business.

Hearsay is the business has been acquired and production may roll again.....................................Then too, I'm pretty sure EPA will be all over it like flies if it actually happens.

I lol'd a bit...

 

[beanhead]

How would you seal rusty damaged threads in an older head? And would that work on a helicoil?

I'd probably start by fixing those rusty damaged threads....ya know, do things the right way. And yes you can seal a heli-coiled hole...it just requires you to be a little smarter than your exhaust bolt...

Good one
Lots of us have been fixing (and breaking) these things longer than you've been alive...so don't expect much sympathy when starting a thread blaming your own lack of knowledge on the designers...

Then you picked the wrong car.

OK...Offensive...

My second car was a 73 Charger that I bought when I was 18...

I've had a 73 Charger as my daily driver for more than 20 years...

I don't like headers...You do...

Did your car come with headers originally? What? No? WOW? Take yer aftermarket crap and...................Think of something...

so tell me oh great Mopar Jesus/ 440 messiah, if it’s such a good design, what are the benefits of having wet bolts for the exhaust studs? People that base their argument off of an authoritative perspective such as “I have all this experience therefore I’m automatically right” are the absolute worst. Argue the argument get off my lawn guy.

OK you young wippersnapper, respect your elders! You asked for advice and you got it. Listen to people who've been there and done it. That's how most of us learned when we were your age. Sometimes it's trial and error but there's things to be learned by listening to experience.

You stating that it was the worst design ruffled some feathers to many who grew up working on these rides and still do.

Would you rather work on this?...

(Yep it's a Chrysler product. Do you know what it is?)

Or would you rather work on this?...

(I'll take the latter any day and yes it has headers that doesn't have leaking studs and bolts. Why? See post #19

We'll help you out on here, just don't bite the hand that feeds you.

Idgaf what is it. I’m not young. I am twice deployed disabled combat vet and current first responder and I’m not going to take **** from some cranky old man because I hurt his precious feelings about a stupid design with the 440. I’m willing to take advice and constructive criticism, but taking **** from someone just because he is older than me isn’t going to work.

Very well said lots are here to help and have many years of working on them . It seems you have trouble taking advice remember that's all it it. Bottom line its your car do with it what you will.

What advice did he offer that I am not taking. He didn’t offer advice. “Learn how to seal the threads” is a bit advice. He decided to be condescending to the wrong person.

Lots said thread sealant its easy as that there are I am sure lots that will work. I am in the same boat just put headders on 2 days ago and doing a motorhome 440 and 727 in this Charger. Lots to do and modify that is the fun of it. Heck alot said crazy for doing a short shaft bolt on yoke 727 but will tell you I will do it. Just try to take things with a grain of salt and suck it up buttercup. There are alot of good ones here that try to help and yes some are cranky keep the faith brother age dosent matter . Thank you for the service.

 

[beanhead]

Okay look. You didn't "hurt my feelings". I could care less if you insult chrysler or me or anyone else. You started a thread not asking for advice but whining about a simple problem and blaming. So I gave a smartass reply.....get over it.
You want helpful advice? All you gotta do is ask...

 

[moparedtn]

Let me see if I got this straight:
A fella comes onto a marque-exclusive enthusiast site (which inherently means it's populated
by people who are fervent fans of said specific group of cars, as originally produced by a specific
company)....
Fella then proceeds to trash the design of a staple engine of said marque...
....and then gets all butthurt when some of these resident enthusiasts come to the defense of said engine/
marque.
Is that about it?

Makes a logical observer wonder why said fella is even on this particular site to begin with?
If one doesn't think Mopar stuff is so hot (flawed, even), then why hang out here?

Reality check:
The engine in question was originally produced for over a dozen years; production numbers in the seven-figure mark. Engines with "design flaws" don't enjoy that sort of longevity, simply put.
Over 50 years after its' introduction, the 440 remains one of the most popular engines
amongst Mopar enthusiasts.
The aftermarket still produces major components for it; and many thousands of owners run headers on them without issue.

Conclusion:
The design, the company that built it and all those who still own and enjoy the engine
to this day aren't the problem here - but if they were, this website certainly isn't the
place to find like-minded souls to agree with said fellas' hatred of the engine.

Ok.... back on track.
James, all exhaust manifold bolts / header bolts go into water jackets on the big block chrysler engines.
Headers or manifolds they each, bolts or studs need to be sealed.
Several good products listed to do that.
All of us listed what works for each of us.
Best way is to work with dry conditions and clean threads no matter what sealer you go with.
Myself I like to let things sit overnight before refilling the coolant.
A perfect design? No they are not. But they are what we have and they do make good power.
Each company has their wtf moments.
Kinda like GM sticking the distributor through the back of the intake to hit the oil pump that's buried inside the pan. Lol.
Anyhow, good luck getting the leak sealed.

Aftermarket aluminum heads, use studs and they don’t protrude into water jackets.
