If your boat was stored on the water and they were wet all the time, you'd have a galvanic (electrolysis) corrosion issue. If it's a trailer boat that doesn't float in the marina 24/7 all summer, I don't think so. The block will drain to about mid-way down anyhow, leaving the top half and the heads dry

Brodix cylinder heads offers a hard anodize coating option for salt water corrosion resistance.As long as you dont leave it in salt water or run strictly in salt water you would have no worries.I seen a pair of used aluminum heads on ebay that were used in salt water and they were rotted out pretty bad around all the water passages, these heads were not hard anodize coated.
