Ron, look at the gaskets. The 351w port is about 1 inch lower.
Maybe George is right. A manifold for a 9.5 would sit higher I guess. Then all you would have to do is either mill the sides to equalize the top of the ports or machine unique thickness spacers.
If you look at the car that was done with the 2v heads, the assembly just fit under the stock screen.
If you raise this manifold 1 inch...guess what?
You can't mill the top down 1 inch, can you?
Yikes is all I can say.
