besides the weight savings of alum heads what other advantages are there....and is it worth the extra $

You can generally run more compression, they disappate heat better. I used Dart 180cc Pro1 heads on my 388 along with its EFI aluminum intake I shaved a tone of weight off the engine, almost 100 lbs from what I remember.

these two reasons are enough to justify the additional cost!

resale will be better as well when it's time to sell.

the alumium heads do not like salt water.cast iron holds up better in salt water.what type of cooling,closed water or fresh water?

The boat actually sits a little higher at rest in the rear now, the previous water line is a good confirmation lol

you can get them hard anodized for the salt water...just bought 2 sets of AFR alum. heads and had them hard anodized them...I got them for use with new whipples, better flow, weight, better heat disapate...

Dart can do this too..........

Good point.
