Coil pack removal 2000 Ford KA

[StoatInACoat]

Need to change the coil pack, leads and plugs to hopefully cure a misfire. Have left the plugs soaking in white spirit as I gather they like to weld themselves in place but in the meantime had a quick look at the coil pack and looks a right pain to get at. Is there an easy way or is it mangled hand time? (again)

Looks like it's held on by four screws from the picture of the new one does anyone know the size of these offhand so I don't have to try multiple torx heads blind and probably mash the bolts up
