318 Build-up Questions

Hey all, pretty new here, but doing a build on a 318 for my Dart Sport and would just like some feedback on the things I am doing from others that have been there and done that.

Block is a 68 model-year 318, bored .040 over and decked. (Side-Note--68 Model year 318s were 9.2:1 comp ratio from the factory) 9.5:1 pistons going in, with a Voodoo 256/262 duration and .454/.475 lift cam (60401). Also have an Edelbrock Streetmaster 318 Intake, and a set of 360 heads from a 78 Cordoba reworked for the top end. Carb decision has not been made so far, but I am just wondering if these changes will give me a noticeable upgrade in power. I basically just want the car to be streetable and fun to drive...long haul plans are to do another engine swap for a 340 at a later date but don't have the funds for this right now as I have found that 340s are pricey and pretty sought after. Thanks for any advice.
