No, unfortunately I bought mine out of warranty and "as-is", previous owner never had the head replaced with the updated version. I only get ticking if I let it sit for a few days, so I don't think I'll be dropping the cash to replace it anytime soon.

I've only spent $350 to get HP gains that you see (would have only been $250 if I would have shopped for a better deal on the intake manifold, but I was in a rush), not sure how much more HP I would get with the updated head, but that is an interesting point!
