Actually, crane had some rockers they sold for Indy SR, B1-BS, and stage 4/5/6 that had slightly more offset for the intake rockers than their “std” rockers.
I don’t know if MP ever offered those though.
MP sold the .485” offset MW stage 6 intake rockers that were made by Crane, and Crane never offered those.
Yes, I think the Stage 4/5 ones were .450" and the St6 MW were .485". They do help on a Stage 6 regular, but the SR's and regular St6 were marketed as designed to "save you money" by using stock (.250") offset rockers. HAHAHA!! #savemoney
