Head re-torque

[Boyscout]

Just a note on re-torquing. Be wary of over-torquing. What often happens is that the fire rings on the gasket collapses, especially between the two center cylinders. You don't need massive amounts of clamping force to seal the head. I have torqued the newly resurfaced head to spec and have had absolutely no issues for the past 10000 plus km's. No gasket compounds or sprays were used either.

A friend of mine, who's engine was done by a reputable, well known Mini guru, had the gasket blow between cylinder 2 and 3. On closer inspection the fire rings had been squashed and deformed. This can only be attributed by over torquing.
