CDH head

[Stoneman]

Has anyone seen one of these heads or used one. Can anyone tell me anything about it?

How goes it seal against the head gasket?

I think I’ve tracked it down to being a copy of a Jake head.

It is a clone of Jake's head and is very good for sealing it has a slight recess into the bore,the only thing is that the sqiush is improper.Here's a pic of Jake's head. You can see the difference in chamber.

And one of the clone's but this one has a sqiush area and slightly different chamber again.
