Default Lt4 Valve Springs

I am looking at swapping the cam in my Lt4. If I put in a Hotcam and stick with 1.6 rockers what springs would you all recommend?

Check out the Crane H-11 tool steel springs, they are a direct drop in for the LT4. Or if you want to spend a little more money get the Comp Cams 918's.
