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.
