Piston question

Any of yall that follow my build thread already know that I have ran into a speed bump with my engine build my block didnt clean up and. 03 or .04 so I'm having to go .060 the problem is I cannot find any speed pro h116cp+.060 pistons in stock summit says they wont be available till September but when I called them they said they dont know if they will have them then either. I have checked alot of places all are out of stock my machinest even called sealed power and we can't get them thru them either. So I'm kinda thinking of going with the kb107 pistons I would like the small bump in compression it will give me but my machinest doesnt like them he said you have to run more ring gap because they expand more or something like that. He told me he would rather run a low compression height factory replacement piston than the kb107s but it was up to me. Have you guys had any trouble with the kbs any body running them now? Let me know what you thing good and bad. Thanks guys
