Seeking info, 12 fpe M-Rod port size regulated

[HunterWhite]

Hello, I am building a 12 FPE M-Rod.  It will be regulated with 177 caliber barrel. I am looking for any threads and information concerning port size in regulated rifles. I think that standard is 0.140. If this is increased to 160 would it have any negative effect on accuracy,  ES, shot count or any other properties.

Thanks in advance.
