broke it were ?the girdel or rocker studs. who s stud girdels? how did you brake the gear drive ? if you want to keep your valves springs from breaking to i would not used the gear drive. it sounds like something hit hard like piston to valve ? coil bind or the girdel was hitting on the back side of the rockers have see this. (girdle to low )look at (the stand off ) they hold the rocker to the stud and the girdle clamps to them . make sure they are not hitting at full lift in the rocker body I have seen this to. this will put the rocker in a bind before full lift check all the push rods to and the lifters. on the lifter are they right ones for the block ? if a mark 5 or6 you need the taller lifter body . is this cam a small base circle cam?
