1JZ-GTE camshaft ball bearing

Hey guys, Happy 4th of July. I've got a question about my cams that I bought. On the back side of the stock camshafts there are little metal ball bearings, thats my guess, now on the new cams there are openings for the metal balls, do I just tap the metal balls in? Pictures below

What came. You shouldn't need to. The balls are to plug the holes from the machining process.

Wow, super late response but; I ended up contacting the company and the guy who I bought the cams from ( Goleby's Parts in Australia in case anyone was wondering) and they said to just tap them into the ends of the cams and they would bottom out.

That’s wired they wouldn’t do it before shipping

Are these aftermarket cams or OEM?

Edit: Nevermind, I see these are probably Camtech.
What duration did you get?

The lobe dimensions are significantly different than stock.

I got their 282 duration cams. Not sure what to expect to be honest
