WD45 Manifold bolts

Changing the intake/exhaust manifold on a WD45 gas. The front bolt was larger than the three others. Is this the way it is suppose to be or did someone screw up the thread and replaced it with a larger bolt?
 
They are 3/8" and go through into the water jacket if I remember so if you remove one install it with sealer.
