No need to remove any engine mounts bud.

Remove cam belt, cam pulley,
Take off your rocker cover and remove rockers,
Take off your dizzy, you might want to mark it first to be somewhere near, but if your changing the spec of your cam, you may need to alter the ign timing anyway.

With the dizzy off, the camshaft should come through the hole, through the gearbox side.
