Properly replacing Subaru EJ25 head gaskets takes patience and quality parts.
While head lift occurs on all engines, the rate at which the head(s) lift is specific to engine architecture, operating conditions and the OE manufacturer’s performance/fuel economy requirements.
Head lift is not the whole head that is lifting from the block, but is a distortion in specific areas of the head and block interface where the head gasket is installed. This distortion can damage the head gaskets and head bolts.

The hot topic of this podcast is multi-layer steel (MLS) head gaskets and how
In the 1980s, many race series were experimenting with turbochargers on stock block and specialty race engines. Huge horsepower and torque numbers could be produced for a short period until the engine self-destructed. What a lot of the engineers and engine builders could not see was at peak cylinder pressures the head was distorting the casting and allowing combustion gases to get in between the head, gasket and block. New technologies like direct injection, variable valve timing and turbocharging are pushing chamber pressures far beyond what they were a decade ago.
Replacing a head gasket is a significant investment for the customer. It also represents significant risk for a shop if the replacement gasket fails. To do the job right, you have to ask why the gasket failed in the first place and what it will take to prevent it from happening again.
