When is it time to change springs?
I have put about 8k miles on my Absolute Speed 5.3 heads with crane dual springs. I am running a 224/228 581/588 +4 cam. Just curious when it is time to swap the springs or is there a test I can run to check the strength of the springs.

In genearal as Judge mentionned it depends on how hard you use the motor, but it is good practice to measure the seat/open-closed pressures on a yearly basis.
compare that to original specs to make a judgement on whether to replace or not.
Singles should be done more often than duals.

Since you don't drive it hard, if it were mine I would check every 30K miles.

You have a ways to go. Im at 26k miles on my 224/228 patriot gold duals. still runs like a champ. I drive mine hard..sees redline many times. I do however follow the golden rule with dual springs. No WOT until oil temps hit 150 deg.

Predator-Z offers some good advice. The springs should be fine for awhile. We have tested several sets that customers have sent in after changing and the springs have done very well. One set that stands out was a set on a G5X3 cam that had 27,000 miles on them that were still at their advertised rates.
