Shimming Evo Springs?

[Yngvar]

I'm about to put some Evo 8 valve springs, into my car along with bc 272 cams. I was wondering, would it be worth the time to shim the springs to get a little more sit pressure? All so how much would you shim them?

You don't need to do nothing to them they can handle those cams easily. BC cams 272 are not as agersive as other cams.
