HyWay - Husqvarna 359 top end

I will have to double check that, won't be too hard to turn down the piston a bit.

What is normal for a saw anyway? .003-4?

It's usually high spots inside the cylinder that need to be knocked down. Use a emory cloth on a split roll to get it to tolerance. I use a stone home to make sure everything is straight and a ball home to put cross hatch back in the cylinder.

It's never a huge amount to take off but it's usually a high spot around a port edge that you will see causing scuffing on the piston when dry fitting it.
