300tdi head gasket re-use

Hi, Iv'e rebuilt my 300tdi engine after having block re-bored and fitted a new 3 hole elring head gasket. Iv'e just taken the glo plugs out to check their o.k. and
the probe on one of them stayed in the hole, so I need to remove the head to sort it.
Can I use the same gasket, or will I have to buy a new one, even though the engine hasn't been started with the new one in?

If it comes apart cleanly the you will probably be ok, if there is any damage at all throw a new one in.

by a new one gaskets is already compressed now

Thanks Kwakerman and James. ''Probably' ok' isn't worth the risk, so I think I'll have to replace for peace of mind. Speed of reply appreciated, Gerry.

I never re fit any gaskets once used .. Always fit new ones ..
