LS7 valve springs work in a big block

I run Comp beehives on my engine. You need to run inside locaters under them or they walk all over the place. The locaters are about .060 thick. The only way i could have used them on my iron heads was to also run retainers that had extra height to compensate. When I switched to Edelbrock heads I was fine, because they were designed with .060 cups for the standard springs so I just switched them out. If you install the springs at 1.850 you will need to check for coil bind.
