If memory serves the stock pushrod length is 7.385. Whatever you mill off the deck you need to subtract from the pushrod length. If you have an aftermarket cam you'll need to then make it longer for the smaller base circle. Milling them .030 puts you right around 10.8 compression with a ~62cc chamber.

Cam someone compare the following two cams?
