In-Reply-To: Mime-Version: 1.0 Content-Type: text/plain; charset="us-ascii"; format=flowed Paul, Having just been through this, I'll try to answer your question. Keep in mind that I am using SS headers, but I think I have an answer anyway. I used the EGT sensors that comes with a weld-on bung. The bungs are male thread on one end and have a shoulder on the other end. Since you have a cast iron manifold, I would drill and tap a hole at each exhaust port and make a screw-in fitting by welding the bungs that come with the EGT's to a second fitting that matches the holes you just drilled. Then just screw them into the cast manifold. Or, if you know a very good welder, drill holes and have him weld the bungs to the manifold. A third approach might be to make new fittings that are threaded on each end. Easy if you have access to a lathe. But I don't, but do have a tig welder, so as they say "when all you have is a hammer, the whole world looks like a nail." You could just thread the bungs into the manifold and then screw the EGT probes onto the fittings. Mark S.
