I'm not familiar with this engine, however, I have assembled many engines were the amount the Cylinder SLEEVE protrudes above the ENGINE block is critical.
Check to verify if there is a MIN/MAX as to the amount of protrusion, above the DECK /TOP of BLOCK that the SLEEVE is allowed to protrude, and, what the amount MIN/MAX of sleeve protrusion is allowed between to adjacent sleeves?

Which engine, early regular diesel or late direct injection? And is the head being torqued again when hot as Perkins calls for?

indirect injection............

sorry should have posted that

Sounds like a previous blown headgasket/cracked head may have burnt a flame path across the top of the sleeve. Check tops of sleeves for any signs of the lip being eroded low. A nice flat hone stone works well to determine this.
