Default another look at reverse cooled heads

How's this for reverse flow cooled heads?

http://www.popularhotrodding.com/tec..._parts_engine/

Through an ingenious distribution system, water is plumbed to the heads beneath the exhaust ports, and returned via the core plug holes in the block.

Appearances can be deceiving, as a look inside the manifold reveals. The plenum intake was epoxy-filled over a plaster mold to effectively produce a single-plane manifold within its confines.
