These are 3/8 stud mount rockers. Not sure which arp stud kit to run. I think the length depends on if I use guide plates or not........ Do I use guide plates or not?

Can't get any help from prw...

Use guide plates if they are not self aligning. Comp Cams has a stud mount conversion kit, which you can look up and even copy or just buy the studs and guide plates they have. If the heads are off the car, you might even consider having a local machine shop drill and tap the rocker bolt holes for a larger 3/8" or 7/16" stud. Might have more options too.
