Paxton and stock internals

My 318 is overhauld, bored .30 over kb pistons, new internals, but everything stock except the pistons they make +5cc. And ive got a mild cam for low end torq. And edelbrock performer and holley 600. Now im wondering can the engine take any boost at all.. ive got a set of indy 360 hi-lax heads coming also.. 62cc but with 1.93 valve..
