The math looks right. 5K on the belt should have that bedded in so your setting will stay.
Mitsubishi calls for the lifters to be purged with fuel oil prior to installation. For your checking work engine oil my be better but for start up fuel oil in the lifters is best.
Without any oil in the lifter you are working with is just using its internal spring,it will bottom out. With fuel oil it will push your tooling spring.
You do not want to start an engine with dry lifters, not good for them.
