Head gasket

[svo58]

I took my head off of the 250es (where the cam and the valves are)now there are 3 metal gaskets,can they be used again when i put it back together.Should i use form-a-gasket on the metal gasket.I don't want it to leak,iwant to do it once.Any help would be great,Thanks .....svo58

dont use form a gasket or any sealer there. its best to replace it . but ive reused them several times without any problems..
