OEM gasket. its not the gasket that is at fault. poor cooling system, wrong coolant used, poor/bad grounds, and may other factories play a part in HG failures.
one thing alot of people miss, even toyota techs when doing the recall is to check the block for pitting. if there is pitting, the block needs to be replaced.
the head should be decked and cut. the block should be decked and if out of specs than repair accordingly
