Crane BB rockers with 0.300 offset?

I have a couple of pairs of new Crane rocker arms that I was going to sell, but now I have no idea what they fit. 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?

According to this they fit stage 4,5,6 and Indy sr

Cool deal. I never thought to check Summit since Crane has been gone so long. 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're intake only and right and lefts.

When MP used to sell the blue versions, they were listed for Stag IV / V heads. 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.

I never knew about that trick

I have a set on a rpm headed 440 for that reason in 1.6 ratio. They are ported pretty good and didn't want to chance it
