the 6.1 has taller stands...so a spacer would only make the pictured issue more exaggerated on the 6.1. Next time we run the clamps i'll look into making the clamps for both designs, But that'll be a ways out, unless I sell a ton of these in the mean time. The 6.1 is pretty sparse in comparison to the plastic intake engines, So I can't re-tool to support the sale of one pair of rails.
