Quick Question, I hope

Hi Guys,
I need some help with my thoughts. A year or so ago I rebuilt a 1990 318ci. I had the roller cam reground by "Magnum Mopar", I think it went to Oregon. I measured it when it came back and compared it to the stock measurement before it left. Looks like they took around 55thousandths off with the grind. I am now getting around to THIS project, 70 Duster. My thought is I need to find pushrods that much longer than stock. Am I correct? The heads are uncut 714s that I did some bowl work to and gasket match. I think I may order a pushrod length checker from Summit to make sure.
Thanks in advance, Kyle
May the 4th be with you! Be safe!
