Does anyone have any experience welding a cast iron water jacket on an old truck engine?

I have a 1925 Mack AC that was allowed to freeze up in winter. The ice blew a hole in the the side of the engine water jacket in teh side exposed wall. The ice sent two pieces flying 20 feet from the truck!. I have the clean broken pieces and have been getting alot of conflicting advice on who can ...and should... fix it. "engine stitching"?, welding?

any experienced welders out there? Anyone know what their talking about? Im confused!

Thanks
