Been a bit since I’ve seen the HS stuff but IIRC they use a different diameter shaft than OE chrysler don’t they???
If it’s the same you can use a W2 rocker next to the HS exhaust rockers you have, although the geometry is different between the HS and the ductile rockers.
Damn...can’t think of a quick and dirty way to get this done. I’d love to see how this turns out.
