Default Valve springs installed upside down?

I know the technical, Subaru, and FSM answer...but anyone have anything other than that to add?

1999 Phase II EJ22 - some valve springs are upside down...didn't know until after the heads were bolted to the engine....does it matter?

And more importantly I've had two valve spring compressors - one doesn't work, it's too large to fit, and the other had interference almost everywhere, working at angles, couldn't grip...took hours.

If I get a proper spring compressor it won't be a big deal to change them.

For daily driving, you'll be fine. If you visit the rev limiter, you will want to change them so the painted ends are up.

Are they a special type of valve springs, bc I've done tones of head work and installed the springs without checking to see if they are right side up or up side down. So in my books it doesn't matter.

Open to advice thou.

great, thanks for sharing! you've installed them without looking and the cars ran fine? i kind of figured they might...doesn't seem like it would be a huge deal.

mine are stock springs - they are meant to install one way. the tops are painted. with paint missing you can tell the difference by looking closely at the springs - they have closer/tighter coils at the bottom.

even once installed you can tell a difference - the properly installed springs will only have like the first two coils touching at the top. the upside down springs will have 3 coils touching at the top because they are tighter wound and closer together to begin with.

of course out of 16 valves - 12 of mine were upside down...GRRRR!

I don't think it will be a problem though I have never put them that way. Like storm said dd it should be ok, for race car fix them.

thanks guys. i ended up flipping them so it's all good. i put each piston at top of stroke and did them on the engine stand by hand. vigorous but possible.
