Need Help! Pushrod Size??

Hey guys I was needing to know what size of pushrod do I need. As of right now I have a set of 7.4's in. It's a 402 Just stock LS6 heads off my old LS2 for now. They are NOT milled. Using LS7 lifters, stock rockers, With stock GM Head Gaskets. I was reading something about the LS2 / 243 castings with non sodium filled valves takes a longer p/r than the ls1 / 243 casting sodium filled valves due to the non sodium valves are a shorter valve stem? Any help would be appreciated.

Thanks
