Default Question on valve spring and cap

I was given a part number for the lt4 spring and retainer kits to purchase for my 1.6 RR swap. The valve springs I can find but the retainers I am having issues locating. It's either been replaced or discontinued.

Any thoughts?
Build will start next Monday.
Doing long tubes, 1.6RR, and dyno tune
