Rocker Studs

[models916]

I had my heads drilled and tapped for screw-in studs (7/16). What LENGTH is used for roller rockers like Crane Gold BBC or Comp Cams with polylocks?

I use 7/16" Big Block rocker studs,I don't know the length.I think if you use 7/16" Big Block rocker studs you should be fine.Make sure you use a thread sealer,because you could get a coolant leak from the 1/8" hole that was used to pin the 3/8" stud.
