Default Exhaust manifold bolts, what size are they supposed to be?

Found a crack in my exhaust manifold last weekend.
When I removed it, I noticed that the 4 outer bolts weren't the same size, what size are they supposed to be?

Are the center mounting bosses of the manifold thicker than the outer ones? If so, that would explain the longer bolts in the center.

I know there middle ones are supposed to be longer. Just wondering what the size of the inner two and outer four are supposed to be to I can pick them up at the local Fastener store.
