The thing is, we know that removing it increases cylinder pressures but we don't really know how much. Without knowing how much, we don't know if removing it has a significant negative impact on headgaskets or not........

Exhaust gas recirculation lowers combustion temperatures to reduce the formation of nitrous oxides(NOx) not to protect the head gaskets from blowing. The process is intentionally inefficient for the sake of emissions. The introduction of a fresh air charge helps to remove heat and control cylinder temperatures otherwise(in lieu of EGR)
