Low pro 3/8 should be using a 1/8 wheel, some of these and the picos might require a 3/32 wheel. You do not want a ton of hook just a slight curve so that the side of the cutter is not leading the top edge. Also make sure you reach down to the oem gullet depth without grinding the tie strap. Keep your wheels dressed to the proper u shape. After a couple chains likely need to touch up the wheel shape.
( note: 3/32 wheels would have to be gotten from a tool supply house, resinoid bond is fine, runs cooler than vitrified apx 46 grit, 60 is too fine and burns. Wheel hardness rating of J would work ok. You will also need to make a arbor size adaptor or purchase one as 1/2 is not that common a size in the tool room grinding industry )
Also I use a head setting of 65 for almost every thing, 25 across the top plate
