300 in/lb Torque sequence is center top to bottom right to top left to center right and then bottom left. And double check that model number Is is possibly 445677-4188-g5 Since the number you listed doesn't appear to be a valid type number.

Number valid just not on Power Portal. I have found several engines lately that is not on the dealer support site.
Listed on PD also in the parts diagram section, but maybe not updated on the power portal yet. I have found a few cases where the parts where not on the dealer sites that were used on JD
