never ever, ever, ever, ever, ever, ever reuse a head gasket. it's just asking for trouble. i'm not saying it hasn't ever been successfully done, but is the risk really worth it?

the material they spray the h/g was starting to bubble on my cometic so i found a new one for 120 shipped, better 120 out of my pocket then to blow it while being driven ....... hard

I thought people were having problems with cometic head gaskets anyway? ?
I've heard OEM or Cosworth were the way to go.
