i think that ridge is for pushrod tube clearance. Pushrods go through the intake on FE engines. [/quote]

That intake in the picture is NOT a tunnel wedge. My buddy has a set of those and the ports are as big as baseballs with a tube right thru the middle of them on the intake side. The heads are also very large with no tube restrictions. He said they do not really run that well because of the airflow restrictions from the big pushrod tubes.
This is still a very nice looking set up. [/quote]

The intake we're using is a tunnel wedge. The intake you are talking about is a tunnel port. [/quote]

My bad Andy.
You are correct about it being a tunnel wedge. My typo as i was trying to clear up the statement "the push rods do not go thru the intake port" on those heads or intake. I should have said tunnel port intake.
Thanks for sharing this post. Sometimes it is fun to see what other brands have available with out going to Yellow Bullet.
