I don't think the reason to swap heads is for weight saving but that is a byproduct of making that change. This tread on OO has some good information but guys are talking of swapping at 700hp and up

usually then I fall back on my philosophy that someone always will be bigger, faster and louder and stick with the basics lol.

I'm thinking of this strictly from a weight standpoint. I'm going from an inline 4cyl to a 302 in a 16ft boat. If I can switch to aluminum intake and heads and make some other modifications on the exhaust side I can probably shave at least 150-200 lbs off the weight of the engine. The "stock" 180hp from the 302 is plenty for the size of boat this is going in.

right on, the weight difference from a new 3.0 to a 302 is 300 lbs so shaving that back off will get it close to stock.

Ok, what I'm finding is that bare stock heads weigh about 50lbs each and bare aluminum are around 20lbs each. So If I swap them out I'll shave about 60lbs. SO the big question is, is $600 for new heads worth 60lbs...
I think for right now I'll stick with switching the intake manifold and exhaust over and see how it goes once it's on the water. $600 right now could really go towards getting this thing on the water a lot faster this summer. I can always upgrade later.

I don't think so...but then again I pump water into the boats I run 
60 lbs isn't that much weight
it's 2 cases of beer, 10 lbs of ice and a cooler
it's 8 1/2 gallons of gas
it's not something I'd spend 600 on unless I was racing.
I think you may lose capacity for 1 person with your new engine vs. your old one but I wouldn't spend the bank trying to shave the weight.
