Wow... wish I could get cams ground for that price!

Depending upon the drivetrain layout, you'd insert a shim of same thickness as reduction in base-circle. This would prevent your hydraulic lifters or rocker adjusters from running out of range. Extra lift comes from thickness of this shim + original cam-lobe height.
