It could be a lot of thing. Air in the fuel, a piece of junk sticking an injector, timing etc

How many mm of advance did you set the pump timing to?

Did you remove the injectors from the head?

Did you check the head for straightness?

Yup, a trip to a mechanic with the right timing tools is probably a good step... if you're replaced the headgasket there's a very very good chance the timing has changed.
