"Stockish" class with 10.8 springs maxing out at 5k (or where I won't go any further at least lol) - Stock cam
How many race nights before swapping springs and what's the typical suggested gap?
Thanks!

-I tried searching for this and couldn't find anything so if I missed a post just let me know.
 
Things have changed some what .
Used to be you changed them before the feature race .
Then every 3-4 events or before a money race then again before the finale.
Now with better springs , locally twice a year at minimum .
Unless your seeing valve float a lot or engine rpm/power is falling off .
Realize that the other components may also need attention .
Retainers , keepers and the valve stem itself needs inspection .

I always went with zero . Just tight enough that you could still rotate the pushrod with your fingers .
If you must use a feeler gauge ; one and a half thousands or .001 if you can find one that small .
