Valve Spring Dampner

hey guys i have a question for you... i have the eddy heads bought completely assembled noticed there is a spring dampner (what i would think to be doesnt look like a spring its flat) would i need to remove this during cam break in or since its not a second spring would i be ok? i am wondering because of this sad fact my cam went flat on the #4 exhaust lobe..apon tear down it looked like the lifter was not spinning and that it just ate into the cam..my lifter bore was free and clear and the lifter spun in bore with my fingers.. called comp and he said there is harldy every a problem with there cams that would cause the lifter not to spin but if the bore is free and clear and spins with ease wouldnt the maching of that cam lobe be to blame? isnt that supposed to spin it? any way just wondering if i should remove that inner spring or dampner before my next cam and does anybody have and good cam recomendatiosn probably going to go with the same cam 294s unless someone tells me other wise haha engine specs are..eddy heads 10.5 1 pistons victor intake i have a 3000 stall holley 650 double pumper 1 5/8 headers exhause just past doors..any recs on cams?? it was a sad day indeed but now im excited going to make some changes..has anybody ran the milodon gear drive..what are those like how noisey are they?
