I just did a head swap with new patriot gold valve springs. I have started it up and let it idle for a while and get up to operating temps etc...I have bigger injectors that i need to put in before I get it tuned but it cant be driven anymore with the new injectors, so will it be OK for the car to see high RPM's on the dyno with only one heat cycle on the springs??

 

they need 3 heat cycles and that is what i did and i havent seen a problem!!!

 

^ Thanks

 

With the mfg. process of new springs it isn't necessary. Its up to you. Most shops let them "heat cycle" while they're filling the coolant system and then its on the dyno.
