Can I restore a Mac Pro with a .dmg made from a 10.6.8 iMac?

Question

Is the above possible?
This article gives the following list of files to be removed before restoring to non-matching hardware:-
sudo rm /Volumes/imageName/var/db/BootCache.playlist
sudo rm /Volumes/imageName/var/db/volinfo.database
sudo rm /Volumes/imageName/System/Library/Extensions.kextcache
sudo rm /Volumes/imageName/System/Library/Extensions.mkext
sudo rm -r /Volumes/imageName/var/vm/swap*
However the article dates from 2004 and the days of 10.3.  In my experience the only one of these files that still exists in the same location is volinfo.database while Extensions has become a directory.
Can anyone offer an updated list of files to remove to image to non-identical hardware?  Or other advice on not having to spend 2 days or so building an entirely new image from scratch.
Thanks in advance,

A standard retail 10.6.8 system from an iMac should work without modification on a Mac Pro. I've done this myself many times. The last Mac Pro model came with 10.6.4 installed.
My MO is:
Repair hard drive and permissions on Source.
Clone Source to another hard drive using the Restore option of Disk Utility.
Test boot the clone to be sure it works.
Connect clone to Target machine and boot it from the clone.
Use Disk Utility's Restore to restore the clone to the Target.
Disk Utility can do this much faster than it takes to make a disc image. Furthermore, DU verifies the copies which precludes problems. Disc images on the other hand can be flakey and unreliable. They are also more easily corruptible than a clone. And, you can boot a clone. You cannot boot from a disc image. Third-party backup utilities can also be used to maintain incremental backups to the clone so you always have a current backup.
