Indy heads which ones ????

Well, they're pretty much obsolete for racing, with the development of modern springs and decent rocker gear. But like I said, they seem to be smart for solid rollers on the street.

Setup is gonna depend on who made it. You have 16 springs, which fit on the lifters and keep the lifters on the cam lobes, the plate fastens to the block in the lifter gallery in some fashion. S/F.....Ken M
