What rocker option for R/T magnum iron heads?

What rocker options for true R/T Mopar Performance iron heads?
I am on hold on a 360 build for one of my darts because I need to find the correct off set rockers,mainly for the intake....
What have you'll use or got?
I believe even mopar performance past 1.7 rockers listed to work on magnum and r/t heads are listed wrong,what is the original part number?
T&D rockers are well over 1300 dollars and will custom make them in any ratio....
