Valvespring retainer question

[janjon]

Hello All:
 Please, if you will, see the attached photo. My 840292 head spent a long enough time at a machine shop that the guy lost a spring retainer and keeper set. Long story short, this was a freebie deal involving holes in ports, and now epoxy, but that's a different deal. So anyway I take the spring to my local speed emporium looking to purchase what is missing, the guy there measures the spring set with calipers, doesn't have the parts on the shelf nor are they available as other than complete sets. So, ordered, received, installed as in the photo. The retainer doesn't cover the full top of the spring as we can see. Am I asking for trouble running this as-is? Actual spring od as measured is 1.54, making it nominally a 1.550 spring I suppose. The retainer measures, 1.400. The retainer is Comp Cams 740-16, labelled as "Steel Retainer 1.437".
 Any thoughts???

Hello janjon:
 I would not worry about the different diameter of the retainer. It looks like it covers the majority of the valve spring.
You do want to be sure that the installed height is the same as the other retainers. That keeps the valve spring pressures the same
as well as the coil bind of the valve spring.
