Anyways, IMO Cams are one of the last things you should do for the power/$$$ ratio.

Agreed, cams should always be part of a package. I think more radical cams would require a increase in rpm to really take advantage of them. I have yet to see a set of cams that produced a reliable increase that was worth the expense.
The Schrick cams have been available for quite sometime yet no one is feeling froggy to jump at them.
