Happened to me also--Ran in first cam [Comp Cam 282S] with all springs in place -- two lobes ground off 30 minutes on test stand -- Installed Same cam again [ plus all bearings &
oil pump] with only outer springs --ran in same way it now has 4000 miles on it no problems--- Reputable local race shop told me I didn't need to remove the inners but after failure I talked to Comp and was told you can get away with on most small blocks but NOT on an FE.. Steve McD
