There are two different pushrod seats for the lifters. If you have the big seat and a small pushrod end that can happen.
If you have the big seat and the correct end on the pushrod it can’t happen. I know this because I saw it when I was putting my junk together and I blew it off. Then I had the rocker gear off for some reason I no longer remember and I had 3 pushrods fall out of the seat and up onto the lip. Bent all 3 valves.
Luckily I had Smith Brothers pushrods. I sent them back and had the bigger ends installed.
I should have fixed it when I caught it but I went against my gut. And got burned because I went against my gut.
