New Rockers Oil Port off Set

Just ordered set of Lifters and Rockers for a 2003 3.7L. In the pictures online it shows the oil port on the Rocker off set. I'm assuming this is to direct the oil directly at the Cam? Also the port hole appears to be much smaller than the OEM Rocker. Question I have, has anyone else installed this type of Rocker and had issues with poor lubircation?

Newer rockers have smaller holes. Maintains better oil pressure/lubrication for the rest of the engine.

I changed to newer rockers on my 04 and no issues. Btw - the snooty kids call them ‘lash adjusters’

So how many Miles since changing?
