The engine is simply not capable of producing EGTs that are high enough to harm anything. Consequently, peak EGT can be used to identify a stoichiometric mixture, and decreases in EGT from peak can be used to establish mixtures richer or leaner than stoichiometric (ROP and LOP). Consider confirming by doing an in-flight mag check, but be careful if you turn off a mag and the engine quits, pull the mixture control before turning the mag back on to avoid possible afterfire-damage to the exhaust system. wheres the evidence to say that that bicycle caught on fire due to excess head temperature?
