Answer
You're welcome, toyota does not recommend using a sealer or cement whenever there is a gasket,the only exceptions is the valve cover gasket, where a small amount of black sealer is applied to the corner areas of the rubber gasket, never use cement or sealer on a headgasket on toyota engines.
