Is this a good combination for my stock 350ci engine?

Edelbrock preformer air-gap intake manifold, edelbrock performer 600cfm carburetor,edelbrock performer plus cam and lifter kit, Sanderson headers, magnaflow exhaust. All this is going on my stock 30 cubic inch engine, is this a good combination? approximately how much horse power will it have with these mods? the engine is going in my 1968 Chevy c-10, and it is going to be a daily driver.thanks, Ryan
