Likely 383 swap-parts advice requested

Hey y'all, I should be going to the shop to take a look at my 516 heads here in a couple days, and I found a couple sets of Ferrea valves that look promising (or possibly Milodon Street Stainless)...sizes 2.08/1.74. Now, I've never really been good with valvetrain buildup, I've usually just bought heads assembled, and went from there. If you guys have some suggestions of which springs, retainers, and locks would be good for a street/strip 383 that will likely never seen above 6,000 rpm. I want to build it with longevity and reliability in mind but still be able to make good power up around 5,500, so if I'm off here, please correct my thought process.
