Hola There
The studs can be purchased at any NAPA or the like. From 1958 to 1978
any 350, 361, 383, 400, 413, etc heads are all the same for the exhaust manifold
holding studs. While there I would also get new nuts and the exhaust
washer.
These manifolds bolt to your car and add power while doing it. Due to
the different length, you will need any local muffler shop to do an "cut
and paste" to match your present exhaust system.

Subject: Re: IML: Problem with exhaust
manifold studs...
If you reinstall the manifold with four bolts, use two
gaskets.
Pulling the head is the safest way to deal with this problem.
If the
job makes you nervous, let a machine shop extract the studs.
It
isn't that difficult, however. Use a *good* drill bit set,
starting
small, and gradually step up the bit size until little more than
the
stud threads remain. Then use an E-Z out, need nose pliers,
or
something else. If you measure the depth of the stud hole,
you
needn't fear drilling too deep. You will probably feel the
bit
bottom out before you begin drilling into the head anyway.
I've
never used them, but a left-hand drill bit set might be a good
way
to go.
