Default 37 aluminum intake stud replacement

Early Ford flathead factory aluminum intake. My carb studs, especially the rear one, should really be replaced. Is there a method to getting the old ones out without damaging the intake?

Can you double nut the stud? They should lock against each other and allow you to turn the stud out.

Vise grips, as tight as you can applied to old stud[s]. Spray with your favourite penetrant. Using your judgement as to how much force to apply to visegips, apply torque back and forth to get stud moving and help penetrant seep down. If the stud[s] refuses to budge, gently apply heat to aluminum surrounding stud, and repeat the twisting motion. Work the stud back and forth a few times to loosen, don't simply crank it all the way out at once; it could seize and snap/strip the aluminum threads. Use your judgement.
To fit the new studs, use the double nut locking method. Could pay to chase the threads in manifold prior to fitting replacement studs.

I've always removed the intake carburetor mounting studs by double nutting as mentioned above. Once or twice I've also had to apply some heat to the area around the stud.

By all means; if you can get them out by the double nut method, use that method. At least the removed studs may be fit for further service, unlike the visegrip method, which will bugger them...
The last one I did [two days ago], I needed to resort to visegrips and heat along with penetrant. Main thing is, once you get them to move, keep up a forward/backward motion to free up the threads, don't just unscrew them directly. Good luck

Brian, Not to be disrespectful, but do you have some special vice-grips that you use for the? I ask this because I have always been able to get better purchase on a stud to be removed (or even installed) using "double nutting". I have a couple of long 1/2" box end wrenches that I use (so I can turn it both ways), and have never not been able to get one out. All of the vice-grips I have (some real, some "off-brand") were clearly inferior in getting a grip on a stud.

Tubman, No, I just use Genuine vicegrips, [not imitation ones], and clamp them onto the stud really tight. This wrecks the stud; it'll be mightily deformed, but will get the offending stud out, although the real stubborn ones may need a bit of heat.

Use a Victor wrench or you will break them off.

Have you ever used your big finger, channel locks to close your vise grip?

Yes I am an animal.
