Longtube headers

Hi mustang community,

I am ordering my longtube headers tonight and i was wondering which gaskets you guys would recommend.

I also heard about these stage 8 header bolts, are they any good? Do you have any experience with them?

What else should i replace when dropping the k member?


thanks.

Ford racing gasket and the bolts that come with the headers do fine if you can hand tighten them up really tight to were they won't back out. Make sure you put them in by hand a few threads. Don't want to cross thread. Lol

Some say it's a good idea to do motor mounts bushing when you lift up the engine and take the k-member off.

Thanks for your response

I will try the ford racing gasket and i hope its gonna hold up well haha

Yeah i think im gonna do the motor mounts while im in there. Should i go poly or just stay urethane? I heard that poly are too stiff and are annoying when daily driving the car.

It should hold up that's what I used and 30,000 miles later NO leaks. Just tighten them bolts hella tight.

And I would do poly mounts since it's gonna be more solid and you'll be up in there already. There is a lot of people that are very anal about the poly motor mounts and the ridged feeling, but they help out a lot. So it'd be up to you.

I'd replace your starter with a mini high torque starter otherwise if your starter goes bad you'll be taking out passenger side header just to get it out. With a mini high torque starter you'll still be able to service it without removing the header. I say this because my starter went bad weeks after putting on my LTs.

With that I'd say only install the 2 bottom starter mount bolts as well. The 3rd is a bit** to get to and will hold just fine with 2.

True the mini starters seem kinda expensive will this one do just fine or is it too big to clear the headers?

That's a OE design so it will be the same size. You don't need a mini it would just be easier to service if needed.

Anything after 93 was technically a "high torque mini" starter from the factory. There is no need to change it out. If you are that worried about heat soak then wrap the headers in that area but I never had a problem with longtubes soaking a 94+ factory starter.


As far as mounts. You want Energy Suspension or don't bother. They are pricier than the ones on AM/LRS/Ebay yes, there is a reason for that. They use a MUCH better compound and made in USA vs Chinese copypasta. They also perfectly mimic the stock rubber mounts as far as how high the motor sits which ensures your driveline/pinion angles will not change. Prothane and the knock offs are known to sit the engine up higher.


If you want to do all the way around you can get both motor mounts and the trans mount for $210 or so on Summit or Jegs. I had all Energy suspension in my 98 and you get a very slight increase in NVH but its not anything uncomfortable.

If you want to do just the motor mounts then they sell them with just those too for $150.

I will say that it is a total ***** to do the mounts with the motor still in the car and the K in place so if you are dropping the K member then now is the time to do it. I'm putting them in my 2000 as well while I have the motor out.


As far as the stage 8 locking bolts... They really aren't needed with 96+ stud setup. The nuts don't back off the studs like the bolts for the 95-down cars would. However, I did have them on my 95 and they work spectacularly well. Get the gasket on, tighten them up working from the middle out and USE A TORQUE WRENCH going to minimum spec torque. Then start putting the collars on the bolts and see how much further you need to go with each one to have the metal collar touching the primary to keep it from moving. The new versions of these bolts have 12 point collars so its very easy to do vs the old style. I may also do the stage 8s on this modular just for peace of mind TBTH. Again, easy to do while the motor is out or the K is dropped.

hey thanks for the response.
i will definitely replace the starter because mine already has a couple miles on it and feels kinda weak once the car gets to operating temperature.
I am going to order the energy suspension motor mounts tonight.
i am also going to get the stage 8 bolts just as an extra piece of mind.
So are the ford racing header gaskets that they sell on AM good? i heard that the bassani gaskets are really good.
thanks

I did a few edits to the above post. The Ford gaskets are fine. Shot you links on where to order from Summit, that is going to be your best price. If you want mounts with red urethane they have those instead of black.
