Thanks for confirming that for me Eric. I have always wondered it that was true! The 'super metal' kit we bought was fairly expensive but saved us about $5000 on a new prop and about 2 weeks of down time which would of been many more $thousands.

Many thanks to you and everyone else out there.

I did exactly that on my 230 inline 6 head! I cast up '180 deg', isolated runner aluminum 4-bbl manifold and used Devcon plastic steel to isolate the siameze ports in the head. I built dams on one side using modelling clay, cut a mesh of window screen as internal support inside the plastic and poured the plastic steel and let it set up. A little grinding w/ a burr blended the ports to perfection. I brazed a rod to the bolt bosses inside the runners to complete the isolation. I used a Holey 390cfm 4-bbl carb. Made equal length 34" primary dual headers. This combo was great, car would climb a rope w/ bottom end torque, great gas mileage, plenty of top end too. See photos of the project in my Journal.

Devcon is what we used to fill up the engine blocks when we were not going to run a water cooling system. The packing has changed so I can not tell which one we used. Good stuff to use in working on heads.

As I say I like it too but it sure is $$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$!! Can't imagine what it would cost to fill a block w/ nowadays.
