Accuracy wont change as long as you are using the same valves, locks, and seats. You can use the same springs if its a stock engine or mild HR setup that probably only has 350-400#s open, but its just a pain in the *** to do all the measurements with the springs from an aggressive SR setup.

My springs will have over 700#s at max lift...there is no way in hell I'm going to be trying to measure PTV and PR length fighting with that when its cheap and easy to swap in a test spring.

 

The cam is 232/240 .595/.595 110 lsa so maybe it's better to use a weaker spring.
