Alignment with ductile-iron rockers?

actually I'm not sure, but maybe just OEM Mopar adjustable rockers. I got them from Andy since he said they'd work fine with my cam/springs, and they have for 1300+ miles (although not 1/4 mile at a time) ;)

I spent an afternoon on the belt/disc sander narrowing the aluminum hold-downs, then installing everything on the heads. I overshot one (sanded too much off) so I had to add a .010 shim. There does not appear to be any binding or interference.
