I do wish to know whose rocker arms you have as GM didn't make them and I'd like to see the bottom side where they straggle the valve tips and the underneath radius that is closest to the spring.

Photos as requested. Who knows who makes them? Chevy contracts all kinds of components. The mfg. code on the part number says 'Chevrolet Performance,' and they have a Bowtie stamp on the tip above the roller. I think you can see that they would provide better alignment than the stamped rockers with the "bumps" on them.

The radius clears the valve spring retainer at full lift. Not even close.
