Jeep Liberty 3.7L 02 vs 03 and Later Bedplate and Cylinder Head Bolt Tightening

Hi there. I bought a 02 Jeep Liberty Limited 4x4 3.7L with a spun rod bearing about a month ago. I just got everything back from the machine shop and I'm ready to reassemble the motor.

My apologies if this has been asked and answered before but I can't find an explanation here or anywhere else.

So here's my question. I've downloaded the 02 shop manual and also the 03 and 06 shop manuals. The bolt tightening method for both the bedplate and the cylinder heads are very different on the 02 when compared with the 03 and later model years. So is there something different about the 02 motor or did Chrysler see a problem and revise the specs? In other words, should I follow the 02 process or should I go with the later process?
