Rb20det Valve Springs Are They Same I/e?

[Rustspecs13]

So my rb20det hasn't been together since this past September, and I'm trying to throw it back together tonight.

And the box my valve springs/retainers/etc were in got thrown around and my valve springs are all mixed up.

But there are about 8-10 springs on the sides that they were on. I have an idea what row was intake and which was exhaust. Which is fine except they all seem to be the exact same. And then there's about 20 springs that are all mixed up in the middle. The problem is every single spring looks identical, same number of coils, height, diameter, and even all the paint colors match.

The other thing is I have an RB25DET I'm rebuilding that's going to be installed in the next month or two. So the RB20 is just a temporary solution. Its going to be run on a stock ecu for now, with a holset hx30 in my S13 here in the states. So thanks for your help!

So I guess no one knows? I can't find anything one way or the other.

Just had a look on FAST and they are the same part number, also if you look online most people sell just a single valve spring.
