You don't need to. Just heat cycle the springs.

Yeap 2>3 heat cycles (meaning warming to operating temp, then letting completely cool off), that is all.

save your gas and keep it under 2k (drive it nicely)
you can go higher but its a nice precaution + saves you gas.

after 2-3 cycles you're safe to take it to redline

Don't go past 3,000rpms, but I see no reason why you would need to go past 2000-2500

If using new lifters do you need to fill them up with oil first?

when installing new lifters you want them to soak in oil over night.

Has anybody ever called the spring manufacturer to see if they're already properly heat treated and heat cycled? I know it's a free precaution, but just wondering.
