Yeah, the folks overseas have to bring us back to earth on things like import duties and shipping. Plus it is always easier to dream with someone else's money and labor LOL
I'll just offer this: I don't think you are going to see much change with the head change and the stock cam. BTDT. It might rev a bit higher and a tiny bit more quickly, but low end torque (where the cammed flow will not change appreciably) will not change hardly at all; a new timing chain will very likely give you more driveability improvements at low RPM's than the 360 heads. And, the stock cam will not take any real advantage of the improved breathing in the 360 heads at high RPMs. The cam is what is really and truly going to control what is going on in the engine at this level.
Honestly, I'd change the cam before I'd change the heads if I was just wanting to perk up the 318 for pure street/cruise use.
