when changing head gasket, what else needs to be changed?

[Dj_Nizmo]

I need to change the head gasket on my SR20DET. I already have a new head gasket, head bolts, exhaust and intake gaskets, as well as the valve cover seal. Does anyone know what other parts are nessecary to change the head gasket? .. any reconmendations would be much appriciated.. [the reason i don't want to get the full gasket kit is because i already have the main gaskets]

check your head for distortion and have it milled if it is. You should really replace the head bolts as well. They are menat as one time use.
