225 Exhaust Manifold Bolts

I am sure this is an ignorant question, but is there anything special about exhuast manifold bolts? Specifically 225?

My motor did not have exhaust manifolds on it when I got it. I am getting ready to install the manifolds, but need to purcahse bolts. Just go down to the local parts store?

Thanks for everyone's help on my questions over the last few weeks. You have helped by alot!

I've used grade 5 hardware store bolts. Nothing special.

 

same here

 

Sources, not specific to the 225, suggest using Belleville washers on manifold bolts, and anti-seize.

And then in later assembly, there is the preferred extra-length brass nuts for the studs of the manifold to
exhaust pipe connection.

 

yep store bought . use anti-seize on bolts .

 

Thanks guys, I will stop and the store in the AM and get what I need.
