I need to be making a choice soon as I will have the money. I was just reading on the 440 source web site on their stealth heads and how good they supposedly flow AND the price is right.. Are those heads as good as they claim they are? What do you guys think? I wont ever stroke this engine, it will remain a .030 over 446. I want to make as much power as I can with it remaining a 446 with the flat top pistons. So, Fast 68 and the rest, would your pick still be the E-streets or what about the stealths? Like I said, I want the best flowing out of the box heads. maybe later down the road I would be able to send them to you fast69 for some porting, but for now they will be used out of the box, besides checking over when I get them..Oh, also, I am NOT against installing a better cam while im at it, so I could use advice on that also!
