Pushrod length after milling heads

I was hoping someone might be able to point me in the right direction on pushrod length for a new build I’m doing. My 318 in my Dart seized and I’m “building” a 360 to replace it. I have a freshly rebuilt ‘85 short block 360 that has the pistons about 0.045 in the hole. I got a set of J heads off another member and CC’d them at 72 CC. A local machine shop that does good mopar work is milling the heads 0.050 and taking some off the intake side for fit. He believes I may need slightly shorter pushrods but the stock may do fine with the non-adjustable rockers. I have had trouble finding a set in my price range. I’m planning on running the stock style stamped rockers. Is it necessary to change pushrods? If so does anyone have any recommendations?
