building a mild Daily driver 318

Hi i am new to this forum and i have a few questions about a 318 build i would like to do.

i would like to build a mild streetable engine around 275-315 hp. When i do this build i would be starting with a 100% stock 318 putting out around 230 hp. so id like to gain around 45-85 hp from the stock set up. I am fairly new to mopar engines so im not sure what i should upgrade first. i have some expirience with chevy 350s but a 318 is fairly different. i figured id start by rebuilding it with new rings bearings ect. but after that im not sure where to start and im not sure what the strong and weak points of the motor are.

I figured id get headers a 4bbl carb with an aluminum intake... the basic stuff. but after that i dont really know what to do next. Maybe a cam or ported heads or new heads??

do you think those basic upgrades and 1 or 2 bigger upgrades will get me to the hp goals i want?

Thanks for the feedback -casey
