Read the Duration section of this link. It explains a bit more about the effects of duration and why cam grinders use 0.050 lift. It's a bit too long to post.

Also this from the HotRod network:

Also: I'm going to just keep my AFR 1399 heads with the 1.9/1.6 valves that they come with. No fit issues with the BOSS302 block. If I declare the car for SS/CS I can run the Combo legally. Aluminum heads any valve size 10.5 lbs/cid. The index sucks O2 (10.30) but I have thrown t he book at my car over the Winter.
