Post Piston /wall clearence

I am building a 383 stroker with a completely forged bottom end. I am using JE flattop pistons, Oliver rods and crank and am planing on using 250,300hp shots of NOS.The compression ratio should be around 11.0 to 1. My piston to wall clearence is about 20 thousants with a ring gap of about 18. Is this to much clearence??. The machinest that bored the block swears it needs the clearence for the pistons to expand. does this sound right to you guys?? I am new to this and dont want to put together my EXPENSIVE toy only to have it puffing smoke time i fire it off. Any advise would be Helpful. Thanks in advance.
