There is a rivet in the MHG which when installed holds the head off the gasket slightly, it needs to be removed.

And if it's doing this ^^^
A re-torque is not going to fix it...the head has to be removed.
Last HKS Stopper I bought still had it.....
Ditto on a retorque WON'T seal it up once the coolant has got onto the Viton.

If the Deck hasn't been cut it only just clears.
It's only 1 rivet at the front side that's a problem.
I use a small pair of sidecutters to squash then pull the rivet out so there's no risk of damaging the gasket or the viton coating.

You will likely have to strip the Viton coating off (Acetone or paint thinner & a scrub pad). When clean, apply a good coat of copper spray to replace the Viton and it should be good to go.

bet it was designed on friday afternoon, of payweek... dude was in a hurry to get home
I have installed 3 different Cometic mhg's they all had the rivet. I know you guys will all poo poo me but I have reused MHG's more than once and know a couple of others that have also, and always had good results. If you are the one to do the R&R on the head, I would re-use the used MHG and clean the dirt and extra stuff but I have never removed the viton from the gasket except to make sure that the only piece that wasnt missing was between the cylinders. If you are going to pay someone I would probably use a new one, as they probably wont be as clean and careful as you.

I'm about to put in my Cometic and I'm not really clear on how to get this rivet out without messing anything up. Can someone elaborate on this? Also, the viton coating, is this already on the gasket or is this something that need to be applied before installing?
