Valve spring break in poeriod

After completing my H/C swap yesterday I let the engine run at normal operating temperature for 20 min.
Is it safe for me to make a few passes tonight at test n tune or should the springs require more time to break in?

One heat cycle is all they take for break in. You're good to go.
