KQ Laser head gasket replacement

[laserpointer]

Hi all. I am new to this forum and would appreciate some help. I have a blown head gasket on my 2001 laser SR2. Is it possible to change the head gasket and timing belt with the engine in the car. It doesn't seem to have a lot of room in the front of the engine to remove the crank pulley. I have the manual and although it looks a bit complicated I think I should be able to manage it providing I can do it without removing the engine. Any tips would be helpful.
