I essentially did the same thing only upgraded roller rockers, lifters, and rods, also went with a comp cam instead of the cam it came with.... If you price out that kit you literally save nothing... I even asked why and they said.. the kit is just there to make it easy for you.. also you'll need a tune and a new torque converter.. and I needed 7.3 in rods not sure wjat tjat comes with... Look up My first start thread from earlier today if you wanna get an idea what it'll sound like.. although the cam I got was a little more agressive than the trick flow one.
