I believe the old camel hump heads lacked the accessory bracket holes, so your assumption is probably correct bob. A plug would be by far the easiest and safest option. Cast iron can be welded, but you must know what you are doing. My boss welded a cast head after I broke a tap off in it one day, so it can be done. [img]graemlins/clonk.gif[/img]
However, the nickel content of cast iron has changed over the years. So if someone tells you they know it can be done because they've welded cast before, keep in mind that the metal makeup may not be the same. If the welder isn't aware of this, he could seriously ugly-up your head.
