The offset is about 0.300 inches which is more than stock, but much less than Victor or Indy heads. I thought maybe Stage V or VI but it doesn't appear to be the same. Maybe B1-BS or something like that? Anyone know what uses a 0.300 offset rocker arm?

Looks like my measurement was close, they spec them at 0.290 offset and I guess it is only for the intakes. Thanks, I'll update my information. Maybe there is someone out there that needs a spare or two.

They were nice because you could run this style in the 1.6 ratio and the additional offset meant you didn't have to worry about pushrod clearance with OEM iron heads. 2021 Challenger 6.4L Scat Pack 1320 100% stock: 1.680, 11.894 at 113.75 (DA 175 ft) weight reduction, wheels, tires, Hellcat air box: 1.661, 11.686 at 115.97 (DA 710 ft) 1973 Challenger 452 ci street/strip [2008] pump gas, DOT radials: 1.454, 10.523 at 126.44 (DA 514 ft)
