A couple of thoughts. If whoever did the head job *didn't* set the valve timing up correctly, that's one possibility. A fault with the EGR system is another possibility- maybe they've mis-connected some of the vacuum hoses?
Last but not least would be something stuck in the intake, restricting the turbo.

Black smoke can be due to overfuelling, advanced injection timing, or a severe lack of air; so take your pick and start hunting...
