Tom, Fallen Hero's Dad has a 216 engine with his Corvette exhaust manifold therefor he needs the wedge. I have a 235 engine and later this year a 261. The intake I had altered, unbeknownst to me is a 216 intake modified for two Carter Webers.
A lot of time and a little bit of money went into that.
In order to make it work on the Corvette exhaust manifold that I have I will need a wedge.
Oops, just read this old post of yours, we're talking the same language.
Your intake manifold, casting 3835527 is listed for a 216.
The 216 and 235 manifolds are not interchangeable because the heat box is different.
It looks like someone relocated the stud on the intake to make it work.
Also the gasket between the manifolds is very large and looks thicker on one side.
I have the same 235 53-55 vette exhaust manifold, casting # 3836108.
Wanted to use it with my 216 2x1 tattersfield intake,
couldn't because the heat box didn't line up.
