Default WRX springs and retainers on ej22 n/a

As some of you know I'm working on a "budget" 250hp engine.

Block stock EJ20G 30,000 miles, fresh seals
Heads 95 EJ22 N/A heads
95 EJ18 intake manifold, wireing and ECU.
Stock exhaust manifold, my up pipe, down pipe, and 2.5" press bent exhaust with 2.5" CATCO cat, straight through muffler.
TD04L Turbo
370cc injectors

Question is the heads: Has anyone used WRX springs and retainers on the ej22 heads? The WRX is designed for a 7000 RPM redline vs the 6200 RPM redline of the ej22. I don't plan on bumping the redline, but with track days pushing the car at 5000 RPM for 30 minutes at a time, I don't want valve float. Anyone have any info? Are they the same? Different? if they are different, how?
