Default What kind of power can be gained from cnc'ed stock ls1 castings?

Just wondering what kind of power is typical of a set of ported and well CNC'ed Stock casting heads.....I have heard that when done correctly...they can make nearly as much power as much more expensive heads. Thanks...

I'd venture to say 20~30rwhp IF DONE RIGHT. I had a 232/238 cam'd application that put down ~435rwhp on a set of ported 241's.
