King is a good bearing. I have used them many times, they measure a bit different than an equiv FM so be sure to check clearances. If I remember correctly the HP is a steel backed aluminum, so it may feel different than you are used to, but they do fineK.
In the end, if it has oil, the correct thrust diameter for the block, and proper clearance at the journal, your power level doesn't need anything fancy, you could go with almost anything. So a good brand name is a step above that
