aluminum heads

What are the pros and cons with aluminum heads in marine applications?.. I hear Edelbroc makes a great set of heads for the HP 500. Is corossion a problem? Has anyone had any experience with aluminum heads? What do they cost?

I would be interested in an answer as well. I used Brodix aluminum heads on the motor in my last cat, but it was a fresh water only boat.

I have heard some say that they would be ok in salt, and some say they would not.:confused:

need to be hardcoat anodized, salt will eat the heads quicker than the fresh water , but even fresh water they will get eattin up just takes longer. best route is closed cooling, imho...

Salt?

So.. How long would a set of aluminum heads in saltwater last?... If they were flushed well after each use in saltwater?
