NORMAL.. BUT WRONG!! you are now putting the incorrect spring pressures on the valve train!! There is about a .100 differance INSTALLED height on the valve locking groove!! The stock heads have a rotator retainer on the exhaust and thus the locking groove is different than the intake valve.. when you install performance springs.. you HAVE to equalize that distance!! to equalize the spring pressures for the valve train!! COOL?? You do this with a different retainer.. ( installed heights are different with the correct retainers ) or with an OFFSET keeper or both!! Get to you machine shop and see what they have!! but as it stands now.. you are incorrect and will cause damage over the long run!!
