Nurgle-y heads for Chaos Warriors?

[wayniac]

Hi fellow servants of darkness, I have received a box of Chaos Warriors to add to my tiny Nurgle themed army and I don't like the standard Chaos Warrior heads as they don't look too Nurgle-like.  Does anyone have any suggestions for other heads?  I think I saw someone use Blightking heads (have yet to buy a box of those beautiful miniatures though) but they look a good bit bigger and I'm not sure how much conversion work would actually be required and I'm pretty bad at anything beyond like extremely basic conversion work

Third Party I think might be okay but I do play at a GW store so it would ideally be limited to bits only with the majority of the model using the GW kit (I think my manager would be cool regardless, but I want to be respectful).  I'd also prefer helmeted faces or having any visible faces be mutated/diseased looking since I'm going for a highly Nurgle-themed oldschool Chaos warband vibe, so ideally only the champion would have a visible face.

Any suggestions?

you could swap out blightking heads but you need to use some green stuff, you could use some plaguebearer heads, your best bet might be to green stuff in the helmets and drill out ther nurgle symbol, carve some damage into it etc.

or you can just put in there the plaguebearers heads. Cause they are nurgle themen, with his resilence they dont need the helmets
