Exhaust manifold

I can't say I've ever seen carriage bolts used.

Stock would typically be a stud in the front and back on both sides, as those go into water. Bolts for all others in between.

I knew I needed more words..
No water jackets.. this is the exhaust manifold to exhaust pipe
connection.. And I have never seen a carriage bolt used on
an engine...
I would think that the manifold would be threaded
to accept the two bolts coming up from underneath
