i need some expert advice here, i can't figure out why all the inner "dampner" springs have fallen apart. they've broken into pieces, the valve springs are rated at .515'' lift max. nothing else is damaged, the guides are fine and so are the valves. the springs on the exhaust side have been shimmed, probably due to seats that needed to be recut. but you can see where the inner dampner springs are hitting those shims too. i run a Comp Cams XE268 @ .480 lift with 1.5 proform roller rockers. pushrods are hardened steel, stock size. what is going on and why are the inner springs falling apart while everything else is ok?? no one at the machine shops seems to know what is going on.. also the valve guides were cut shorter so nothing would hit. someone help me figure about this mystery... thanks
