452 heads

Josh, it all depende on who ported them and how good a job they did. If they know what they're doing, then they may well be damn good heads. On the other hand, they might not flow any better than a dead dog. That's the chance you take when you buy heads already ported. Does he know who ported them? Do they come with flow numbers? I'm not sure I would want to spend the money without proof. I know that doesn't answer your question, but I don't want to see you get taken. Happy Thanksgiving to you too.
