340 rings

Gentlemen,
Just got call that my 340 is done at the machine shop for my new to me 72 cuda. Block was .30 over prior and it was sonic checked and cleaned up at .40 over. I went with KB243 pistons and on Mancini website they call for 4000AM8 rings. Searching these rings I notice they will list at 4000AM8.030 which shows for bore of 4.030. I am assume I will need 4000AM8.080 since 340 is 4.04 +.040 over bore. Am I correct it saying this?
