What do you think about them? Mixture is ok but too hot plugs?
Any help will be greatly appreciated.
New plugs needed, it's all but impossible to read a plug that is old or has been idled after a WOT run. Your plugs were hot at some point, though. Besides the other suggestions, be sure the heat range isn't too hot. Be sure the timing is all in at or before 3000 rpm and that the timing advance curve
is set up correctly.
