First engine build.

Talked to a csr at Competitions Products today and he recommended this spring kit for my heads and xe262 cam. The first is the spring, second is the kit:

It is a little cheaper than the comp spring kit, but is a dual spring compared to the comp 901 springs. Is there a big advantage to dual springs in my application, I know you should remove the inner spring when doing cam break-in. Or would the single spring comp work as well or better and be easier for cam break-in, for a bit more money? Right now I am leaning towards going with the comp spring kit with 11/32 locks and retainers.
