After doing some further research it seems nothing is readily available for the 292 chevy but two (2) prototype crossflow heads in cast iron exist for the Ford 300.

Board Member FRENCHTOWN FLYER is in possession of both them. Apparently, they were developed by Ford for UPS for a project that was eventually shelved. As we all know, these mills can produce alot of low and mid RPM torque which is perfect for marine applications.

I'm trying to put together a fuel injected marine engine based on the 292 chevy or the 300 ford.

It would shure be nice to have an Xflow head so that I can have a water cooled exhaust manifold custom fabricated. It's a lot more challenging to do this when both intake and exhaust ports are on the same side of the head. The other benefit of the Xflow is that I can keep the exhaust heat away from the fuel rail and avoid any problems or that sort.

I'm wondering how much it would take to persuade the FLYER to let us look closer at that prototype design and have a few more castings made of them in iron. I imagine he'll not be wanting to give up his competitive advantage too easily!
