titanium Posted March 31, 2005 Share Posted March 31, 2005 I'm looking into getting some aluminum heads to lighten up the ride a bit and these dont seem to be priced that bad. http://froogle.google.com/froogle?price1=600&price2=700&btnP=Go&q=Dart+heads&price=between My question is how much better are these comparied to my stock vortec heads that I have in there now? Whats the difference between all the ones listed there, they're different part numbers but besides that I cant find them. Do these heads benifit much from being ported? How much more of an agressive cam can I put into it? What gains can I expect? Thanks for any help. Quote Link to comment Share on other sites More sharing options...

titanium Posted March 31, 2005 Author Share Posted March 31, 2005 Geesh, Well I planed on new heads down the line anyways. I'm just looking now though. I currently have a Vortec 350 SBC I dont know if thats enough information or not but I'll look at those links. Thanks. Quote Link to comment Share on other sites More sharing options...
