DART IMO has always produced a quality product from what I have seen and have listend to their customer base to make an even better product the next time around. That is what I believe they have done with their as-cast LS1 head. And it will be awesome when they come out with their cnc program for the heads they will be even better. And like Mj said Patriiot heads dont need a core you are getting brand new gm castings and they flow almost ecastly the same within a few cfm. They flow a little better down low but flow better up top and the price is definately right. I got my DART heads for 1050 and that is 250 cheaper than the WCCH heads and Im getting a new set of heads and they arent already maxed out to their potential they still have room for improvement but yet they flow almost as good as the WCCH heads fully ported. CFM isnt everything I realize but port velocity will be better due to the smaller size runner and the design of the runner is superior.

No I dont have my heads yet they will hopefully be here next week. I wont be able to get any dyno numbers showing their performance due to the fact that they are going on a 408 that i(and mjhoward) am building.

Im not either man Im just showing other options out there and why i went with what I did. they are niec heads I just couldnt see spending that kind of money when other options were out there that were better IMO thats all. I almost bought a set from Richard but I wanted something that the stock gm casting couldnt provide. Now he did tell me that he is working out a deal with edelbrock I believe that is making their own casting too and that he will be working on a setup for those now that would be sweet too but they were going to be like 2400 bucks and thats way too much IMO. The cnc program for the DART heads will be around 800 bucks so that brings me to a totaly of 1840 bucks and that seems more reasonable to me.

Its cool, you got a sweet deal on the Darts, Did you get one of the first sets? I saw the edelbrock heads, I think they have something to do with Lingenfelter also. They were kind of pricey.
