Ok, I'm almost ready to pull the trigger on some good used heads, GTP stage 2s, milled 20, with 918s. If I go with a mild cam (CheatR, 224/224) how often should I expect to change valvesprings?

This is my DD and I roll 25k+ miles per year. Trying to make an educated decision here...

TIA,
Jason

You wouldn't have to replace them very often as long as you break them in properly and don't over-rev. Those will hold up on that cam just fine. I would say you wouldn't have to worry about it for a long time.
