Two sources give valve guide separation for the LS2 as: 1.913"

You probably already have that information.

Thanks for the effort. Its not the end of the world, I was looking at using the rockers on a project and was curious to the original guide centers were.

I saw 2.01" mentioned for LS3 valve spacing vs ls1's 1.91" but I'm not sure how that compares to valve guide measurements.
