Rocker arm location after head work

[Tigh]

Curious if this looks ok. The heads had bigger valves installed which seem to have a taller stem. The rocker arm sits back a bit farther than I normal. By Buddy ran the heads on his 5.3 and he said there was no issues but I’m still wondering if there is something that would make the rocker more centered, like a longer rocker( I haven’t been able to find any) or grinding the valve stem( not sure if that’s a thing) any help would be greatly appreciated.

This answer is likely late by now.

Here is a pic from my 05.  The angle is a little different than your picture.My take is that if your picture is showing a closed valve, you are likely okay.
