I didn't see any performance parts in the for sale area. I did read the post about the buy out and I saw some parts there I'd want if they was ever made, especially the DOHC 24 Valve head set up!
If there are some specific parts you would want, put a post in the wanted to buy section. Also use the search function. As for that head, I wouldn't hold my breath, if I were you. It could be done, but the majority of slanters are "frugal", and the price of such a head, would be out of reach except for a very, very few, not even counting develoment costs.
