Reply to "Header temps"

Questions,
Aluminum heads? rpm at idle? cam?
have you done a Leak down and compression test, even a exhaust gasket undersized can effect exhaust temperatures.
Any pr-ignition knock?
By the way I had very strange and varying problems with Champion plugs,I now swear by Autolite. Dropping the plug temperature will in turn cause a richer burn. You can do the WD-40 test on that intake, that could enplane allot if you have any leaks
Last question, does the engine overheat? May not be a problem.
This may help these are EGT temps @ 3200 rpm average 1200 F
