Years ago Hughes sold Dove's rockers, but later changed to Probe's parts. When Probe got out of the rocker arm business w/in the last couple of years, Hughes picked up the tooling / whatever from Probe to have the Mopar rockers made.

I've run the Probe/Hughes stuff on the street for thousands of miles w/ 400#s open pressure (solid flat-tappet + Schubeck lifters). I'm in the process of putting together my first solid roller motor that will have 600#s open pressure and have bought new Hughes rockers to use w/ my new Victor heads.

I'll be keeping a close eye on the valve train, regardless, but expect the rockers should be OK from my experience to date.
