"Ok - I have a set of 496 manifolds and risers. My question is...is there any way to make these fresh water cooled manifolds? It's my understanding that they are raw water cooled, and the Mercruiser 496 Mag system is technically a 1/2 system as far as fresh water cooling is concerned (fresh water cooling to the block only).
Note: these are going on a 454 build as an upgrade (they flow MUCH better than the models of old and have the added benefit of a dry joint at the riser.) I just want to make them FWC, and need to buy the necessary parts."
