I believe these to be Mopar Performance Heavy Duty Stamped Rocker Arms
Back in the '90s an older brother of mine briefly ran these on his 440 and switched to adjustable rockers, they're like new with very few miles and have been in storage since then
Also included is the matching set of rocker spacers and standard length pushrods
