Ok I think that I'm close but here's what I have.

the only differance is I want to put a 6" radius on the 3 outside corners of the box and the 1 side of the port how much will this change the box size and the tunning? I will also be making a plug for daily driveing. So just need to know if this should work or what I would need to change.

With a 6" radius, you loose approx 3" off the port length (about half the radius) so you can simply make the port 3" longer... or do it the other way around (word wise) and make your 6" radius, and then add your port board but make it 3" shorter than what is recommended.

Should get you really close. But you do have the little odd portion of the 4th wall being flat. Id probably do as above and see if you need to cut an inch off from there.

Thanks and have a good weekend,
