Could use some help identifying some roller rockers

The good news about buying new rocker arms for Magnum heads is that they are SIGNIFICANTLY less $ than for an LA head. I just bough Harland Sharp Adjustable RAs from Jegs for $500. HS non adjustable rockers are about $100 less. Much cheaper than the LA $1000 plus price for rocker arms and shafts.
