A while ago I had noticed that my exhaust manifold was broken in two so I bought a new one from JJ, I was just getting ready to put it all back together for a winter runner truck and I noticed that the threaded hole on the head was broken in half. Anyone have any ideas of what I can do to fix this or do I just need to swap out the head. Also does anyone have the correct name for this piece? Threaded hole sounds dirty. Sorry if this is a very obvious question or something that any competent mechanic should know but I am not competent. Thanks.
