Here is the gasket, one of the layers is warped and has a fair sized gap.
Took some pictures of the bottom of the gasket and where it came from incase anyone sees anything worrying?

Ouch! That's toast... Goes without saying that you want to get a decent straightedge and check the block and head for warping as per the Haynes manual (and presumably the Honda workshop one too). As per the other thread on your overheating, get genuine gaskets to replace. Even if the other one hasn't gone, I don't think you've had them in there and sort of time, and there's no telling if just having one genuine one might end up killing the other pattern one in the same manner as the weakest part will usually break first. Bite the bullet and replace both, it'll take longer and cost twice as much in the short term, but you don't want to be having the other head off in a little while because it's partner failed in the same way.

Sadly, while a lot of pattern parts can be both cheaper and better than the genuine ones, this rarely seems to hold true with gaskets for motorcycles. Still, as long as the head and block haven't been damaged by excessive heat, all it's cost you is some time, money and effort. Granted, that's not much consolation, but it could have been worse!

Yeah ive got a couple genuine ones i will fit, ive decided i better change both as this is the second time already, and its quite a pain!
Just a heads up, these gaskets that are toast i got from this kit on wemoto:

I also used the exhaust and rocker cover gasket but these seem to be fine, havent installed any of the rest.

But again thank you for your input.
