I will say that durability can be fixed with nothing but a server setting edit, but as far as the food poisoning is concerned, I'd have to do a bit of research to find what I need to edit.

you let me know if you need a list. Boy howdy I can make that list for ya.
That's a whole playthrough right there.

This mod is a winner. you get a thumbs up.
next on your agenda....

Maybe eating raw meat without getting food poisoning or swords that don't loose durability like they are made of plastic.

I didn't know that...I just never tried I assumed they had to have one. Ya learn something new every day ;)

but I would still like to see a system allowing the placement of virtually anything where that head goes.

You can build golems without heads. In vanilla, the head provides a phat pile of hitpoints and additional effects where relevant, such as the explosive head or lightning rod.

You need to make a second mod called "use anything as a golem head"

And consider this. SOME Golems have exploding heads. if the head is so important how is it that the Golem is in no way inconvenienced by removing the head entirely and randomly replacing it with a jar of explosive?

but... there's nothing IN that head! If you ask me they don't even need it, it's purely aesthetic in terms of visual implication.

where it not for the fact that you cannot build a golem without the head in game I would think it served no use at all.
