Gore movies

No way. Neither the 68 version or the remake were.

You can't get much gorier than the aforementioned Fukci flicks, especially City of the Living Dead. The thing is, the overdubs and pure cheese factor of the movies make the actual movie kind of unenjoyable.

I'd recommend "Maniac" as well.

The original Toxic Avenger is fun to watch. Some of the sequels ruin the character. Yes they were more bloodier, but it just wasn't the same.

Evil Dead
Freddy V Jason
Kill Bill
