MG ZR: Cams & Maps

[lolsteve]

oh way to having a new gasket and a running car again. However..

When I dropping the head back down I saw a bit of oil drip from the head onto the gasket out the corner of my eye. 
In my desperation to get the engine back together and headbolts in I whacked the bolts in and torqued them up as was getting tired (back was hurting from trying to lift the head while bent over)  and annoyed of the local kids all stood around asking me questions, touching my stuff and just being irritating little...

Is this likely to have rendered all the work for naught? The engine is halfway to reassembly as belts are on
Or will the clamping force be enough to squeeze out any oil between gasket and surface 

Very disappointed in myself for rushing the job as wanted to do it properly but the lack of garage means I cant spend more time on stuff

Also if an engine hasnt been turned on (eg no heat cycle) could the gasket be reused? this gasket type doesnt seem to compress much or at least not as much as the mls.
