10 Day Magnum Swap - '65 Dart 270

ValiantOne said

Okay I wasnt imagining things. It was over in the 64 Dart GT swap thread. His experience/post noted that:

The manifolds will bolt right on but will have a 1/4 inch open spot underneath where there is a port mismatch. These are the 69 hipo manifolds I'm talking about.
I made 14 gauge steel plates and cut the hole to fit the head port size and the cut the outer edge to fit the manifold.
A better bet would to use magnum manifolds, if you can find some to fit.


Yay, nay?

Here is a link to a post I made about the same issue with a picture. 5.9magnum questions

In the thread I mentioned that I only had the exhuast port issue with the MP R/T heads and not the factory heads my buddy had laying around. My issue was because the material around the port stopped just below the port, but the factory head was cast all the way to the deck surface and then machined. Not sure if this changed, but I assumed it wasn't an issue with any of the factory heads, only the aftermarket R/T head. Not sure what the EQ heads look like, either.
