Well, I finally got everything together for my new motor cam break in. It fired up, ran and got extremely hot, I let it get about to 210 then I shut it down. First, is it normal for the headers to get really cherry red/orange 6-7 minutes into break in? Next, I fried nearly all my boots on my plug wires. My drivers side header caught fire during the break in down near the collector. They are the painted hooker 2210's. I don't know if it was the paint getting so hot it caught a flame, or what. Now, (i think this is the term) my oil pressure sending unit, the unit above the oil filter is all melted and deformed, it is a good 1-3/4" to 2" away from the header itself. Now I am about half way in to the cam break in procedure and all of this has happend already, I don't know what to do. My motor is a 355 with dart iron eagle heads with the 215cc intake runners and 64 cc combustion chambers. I have a solid lifter camshaft. Any ideas on why this is happening to me. I have too much money invested in this already and don't want anything bad to happen. I need help badly. This is my first real motor break in, it ran pretty good btw untill it heated up really fast. The first attempt i wasn't using a thermostat, the next attemp I did. It didn't seem to make a difference. I have my electric fan wired up to a switch so that was on at all times. Can somebody give me some tips or help me get this thing to cool down?

Any and all help is greatly appreciated.
