Pushrod Type

I have a 318 I picked up (disassembled) and it didn't have push Rods but i have J heads I just picked up and the seller gave me these rods for nothing. I attached a picture of one of them. The length is correct. Would these work or are the ball end style more appropriate?

Thanks for the help :)

That's the stock pushrod...

The stock non-adjustable rocker arms used a ball and ball pushrod... (ball on each end...)

The adjustable rockers used a ball and cup pushrod...
