Cost for labor on stroker build?

I had a SB ford built by a local Maryland shop in 2017 so I'm sure prices have went up since then. I bought all the parts and they did the machine work and assembly. Bore, Line Bore, Balance, Assemble, Piston Pin Adj, Cam bearing install, deck block, file fit rings, deck mock up, plain cylinder heads was right around $2000.
What do you mean by piston pin adj?
