Cam kit with stock pushrods and rockers?

I've not had any issues running a 318 with a Howard's .480 lift with hardened pushrods but stock rockers and shafts since 2019.
All I had to do was shave a few thou off of the guides on 302 casting heads to make sure the seals had clearance.
You may want to check the .470 side just for reassurance but it's pretty safe MOST of the time.
