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
Thanks for replying
Sounds like someone just used what they had. It doesn't sound like your manifold is threaded so you can't use studs. I would use Grade 5 bolts and nuts.
