The big thing is to check every one, not just random springs. If they all check out, then years of sitting or running doesn't matter.|

You would need to check them all the ones that were down may be weak. But still able to run for a while but as the miles tick by they will also be the first to fail.

They all need checked on an individual basis. It only takes one weak spring to ruin your day.
I would have them dissasembled and checked, properly. Then make a decision. If they are good if they are shaky or one or two is borderline then ...

how old is too old for valve springs?
my heads were on an engine in storage with the rocker arms still tight for 25 years. water got in the intake and they have already been redone. but the guy said the springs were okay and re used them all, they never got rusty, but still they have had tension on some of them for 25 years. in my opinion they must be junk, and he should have changed them. this is on a relatively low revving (below 6000) pontiyack motor. your thoughts?
