motor build

[straitnate14]

I got a question for you guys? I got a stock 350 with a 142 supercharger on it, I want to do a head and cam swap, would this head be good for the supercharger, http://store.summitracing.com/partde...S-30400013-CNC
and would you think that I would benefit from doing the bottom end while i'm at it? the motor's a 290hp gm crate with maybe 3000 miles on it I want to put 8psi on it I was thinking about buying this rotating assembly so that in the future I could throw more boost at it with a new blower

and as far as the cam goes i'm lost, if you guys could point me in the right direction I would be very happy
