If you planning on staying with the 3/8 stud diameter then I would buy a set of FMS blues, they are cheap and a really good rocker. I upgraded to 7/16" stud so I bought Trick Flow rockers, which are the exact same rocker as Crane Cams Gold Race, except a lot cheaper and black in color.
Also your going to need to check your new pushrod length and order new pushrods. May also want to look into replacing your head bolts or even going to studs.
I use 7/16 stud Comp Pro Magnum 1.6's. We were just checking the geometry and they look great. I have heard of some rockers not working too well with twisted wedge heads, but no problems with with the pro magnums.
