Alot of the temp you see depends on the distance from the flange you are. I have 3 different sets of headers and I suggest the probes all be the same distance from the flange. Ideal would be 1 3/4 from the flange and alcy should be around 1150 to start and tune by the plug, as mentioned.



I have seen more than one expert say that ideally they should be in a spacer between the head and header. The closer to the head the better.I install mine as close as possible on the dyno.
