It appears the outside two bolt holes have solid studs and do not require any type of fastener. Is this correct or should these be bolts? I would think it would not seal completely. I have the retainers all in place and torqued correctly.

years. Installed properly I've never seen one leak at the
ends unless it was warped and needed to be machined flat.
Now the exhaust flange is another story, I must have blown out
a dozen flat gaskets between the manifold and exhaust pipe flange.
Back on the studs. They are often removed and replaced with
bolts on the stock manifold and especially when installing
headers where they really are necessary. The rear one can
be kind of a bear to install.
