exhaust studs

You will find you may not be able to fit the exhaust manifold if the studs are to long especially with the tubular headers supplied today. I use socket headed UNC cap screws rather than the original studs for that reason. Just make sure the threads in the head are clean and use plenty of nickel antisieze on them so they come out cleanly when needed.

I went the caphead route, making sure the threads were clean beforehand. Could I have some information on a recommended brand of the nickel antiseize please?
Thanks

Perhaps you guys can give some thoughts about getting bolts out where antiseize may not have been used. The exhaust manifold in my Elan has had the original studs replaced with what appear to be ordinary bolts. However this was done some years back in South Africa and I cannot trace anyone to confirm the build, but I suspect they may have been replaced without antiseize.
I need to remove the manifold but am mindful that they may not be easy to remove, so any thoughts gratefully received

I use Bolt Buster

There are a few new/cheaper ones out there. If your brave enough, an old coil ring element works. Propane gas will get it warm (i bet it will work in ally head), maybe best to soak for a few days with quality penetrating oil. Then again, brake fluid is the best penetrating oil known to man-kind.
Take a pick tool and scrape around the stud, so you expose the head.
good luck, I will be doing mine next week!

Find out where the limits are, and start from there

Many threads in the head get damaged when people who are fitting the Manifolds force Studs or Set screws in.
Before putting All the Screws/Studs you should put one in at the end to see how others line up.
Adjust Manifold so ALL holes line up WITHOUT forcing in a free state.
Then you can easily wind in with your Fingers the Studs with "Copperslip" on threads (that's what i do).
If if you prefer Set Screws/Cap Screws with your Fingers.
I have never damaged a Thread in the Head doing like this.
