exhaust leaking. help

[ellis_12345]

changed the headgasket not long back and since ive put the manifold/exhaust back on it keeps leaking between the manifold and the front exhaust section. ive took it apart and jiggled it about but it still smokes a lot every time it gets up to temperature. help :tard:

Try a bit of exhaust gasket gunge on the seal?
