Bolts on top, rear of head

I'm in the process of putting my new head together, and I transferred all the bolts from the old head to the new one (not the head bolts! The ones for the exhaust manifold, etc.).
There are two bolts on the top rear of the head that I believe the fuel rail mounts on. These bolts are fully threaded, preventing me from using vice-grips to get them out. I'm assuming that I would need to purchase these bolts new to install.
Does anyone know a part number or where I can order these from?
