Cyl sidewall wear with a 416

I have the heads off the stroker I bought here:

To get the springs checked to be sure their tension has not dropped and to get them flowed. So looking into the cylinders I find a bunch of wear where the piston skirt would rub. There is the nice light crosshatch except wherethe skirts rubbed about 1/2 way up the stroke travel (2 - 2 1/2 inches from the deck) which are worn smooth. Also the pistons rock on the pin a lot more than I would expect and at TDC they also slide side to side on the pin more than I would figure. The pistons are KB forged 745.070.3 and per the build sheet I got with the motor have 0.005 clearance with the freshly bored cylinders.

Is this kind of side wear on the cylinders normal with 4" strokers? Should I pull these and either get them coated or put in a new set which has the skirts coated? Man I hate the thought of having to pull it back apart cause then I would probably end up doing stuff like putting in a Hughes girdle which will require align boring the mains again (maybe). Plus then I would probably put in a bigger cam and different higher compression pistone... in other words a rebuild.

The story was this engine was built, dyno'd, then pickled and sat for the last 3 years. Who knows, maybe it was run hard and put up worn out. BTW, the nitrided cam looks about new with all the lobe tips still black. the flat hyd lifters have a circle in the center, about 1/2 the diameter of the rocker, that is kinda yellowish brown. When 2 lifters are put flat to flat they still rock a tad.
