Here is another cool thing done on this engine. The heads are preheated to ensure correct loads when torquing the heads down. Two heat guns get each head up to temp. It is time consuming and smells terrible, but the aircraft sealer is melting into the surfaces and then is cooled slowly to set the "goop". You can see the aircraft sealer on the closest head/block/gasket line. This sealer turns grey/brown/black after it has cured. Copper gaskets won't need a retorque this way. Below is a shot of the first gun running.

Here is what the head temp is up to so far.
