If you mill .100 off your head new head gasket is about .020 thicker than stock wouldnt your pushrods simply need to be made about .080 shorter than stock?

Did you change your camshaft? Or is this the only change you made?

Always "mock-up" your combo and take actual measurements before ordering a custom set of pushrods.
Many times things will "stack-up" right and the stock length will work fine.

When you install a larger cam shaft than stock, the base circle of the cam also changes. The only way to be sure on the length is to assemble the engine and check it. This way you only have to buy one set of push rods.
