which bolts in water jackets?

[dodgefreak8]

hey everyone I was just wondering which header bolts are machined into water jackets on a 318?? I need to switch gaskets and I really don;t want to drain the antifreeze. I have studs in the front and back holes and I was hoping these were the ones into the jackets but I can't remember now.
