It IS NOT the torque an engine makes that causes the head gasket to blow/head to lift IF the timing is not correct you will have spk knock /pre ignition this causes as much as or more then 10 times the load on a cyl , A built Focus engine as proven to with stand much much more then the TQ he is making , on my engine , Sean Carlsons engines and many others , Jim isnt having this issues and he drives his

You need to check and watch your knock sensor there is a TON of information you can get from it AND it will keep you from having this issue again

Head bolts dont stretch from this low amount of TQ your making , heat your making has nothing to do with your problem unless your passing 240 deg engine temp, dyno vs street has nothing to do with your problem , you have excessive cyl psi from pre ignition THATS what causes the head to lift

On a side note to that if the heag gasket isnt TQ 4-5 times that also is an known issue on the Focus

Allegedly

14:1 compression is nothing. If he is running 9.5:1 with 28psi that is an effective static compression ratio of 27:1 But you knew that... or did you?

The esslenger cars had o-ringed decks.

The headgasket isnt just blown, the head has a huge melted hole in it. due to excessive heat, timing, etc

Once the gasket goes you are forcing superheated gasses through a very small hole it doesnt take long to eat a huge hole through the aluminum. You dont just blow a hole in the head like that the gasket has to go first. If it were in the same exact spot both times I would say it was tuning. There is always one cylinder that gets less fuel than the others, it is in a different spot but the same result.

Shouldnt be melting the head, even if it is lifting, which i dont think is the problem.

I would say this is a "slight" build.
