Need info on doing headgasket on 2.0vvt renault megane

Hi Headgasket has gone on my 2005 megane cabrolet 2.0vvt however I cant find anywhere any information on correct way to remove the cylinder head or even torque settings/ tightening sequence. I've done plenty of HG before on Honda and Peugeot engines but I cant even find a Haynes manual with the information I need. Any help will be great guys because I cant find anything on the net.
