Can someone tell me if all nytro heads have this restrictor? I put a new head on my nytro and don't remember seeing this installed. I'm pretty sure I would have noticed it when I was prepping the gasket surface.
I was cleaning the gasket surface on my old head, noticed this and then didn't remember seeing it on my new head.
Basically, want to know if I have to pull the new head if it doesn't have this restrictor?
Thanks.
