With the engine locked up, it will be an extra challenge to get to all of the pressure plate bolts. If you pull the head, you might be able to turn the crank shaft. Sometimes a frozen valve stem locks them up.
If the flywheel has the original bolts with the locking plates, you will need to use a punch to flatten the ears so the bolts will come off.
