Let's see IIRC there should be three. One on either side of the center ports on the drivers side used to fasten on the heat riser and one forward of the center port on the pass side used to attach the battery cable ground to.
Of course then there are the head bolts under the valve covers that may or may not have studs on top for oil drippers depending on the year and if it came with them. I believe there were three bolts in the middle of the head on both sides.
