He is still worrying about the springs before the cam choice.

The Comp single coil 972 spring has the same 1.460 O.D. as his current springs and rated 124 at 1.800". That spring uses the 744 retainer.

My comments were hypothetical. I did not look at any specs for the retainer other than a cross reference that suggests it can be used with the 972 spring.

Curious. Like the two or three others following your 'progress' which valve spring are you going to use with that 743 retainer?

IF it's the single coil 972 spring remind me to tell you a story about breaking a valve spring while leisurely cruising down the road.
