One thing to consider is matching your top end parts. Many manufacturers design cams, cam gears, valve springs/retainers, etc. that will all work together. When you start mixing and matching brands, you have the potential to run into problems. Many companies will warranty their parts if you use everything together, but say you break a JUN cam while using Skunk2 cam gears, you're going to out of luck and $$.
I've seen a few pics and heard a number of stories of Crower cams breaking. I'm not saying don't get Crower, but it's something to think about. Consider other brands like Skunk2 and JUN. Prelude Type S cams may be another option, but I'm not too sure if they are a drop in.
