Personally, I chose the Malossi. I know that aluminum has better heat transfer, but my s9 is a daily driver so i like the reliability of the Malossi 70cc kit.

I have a cheaper cast iron 70cc bbk on mine. Works very well, but I imagine the malossi is built better, ported better perhaps.. I know a few people that swear by the double ring airsal. And then a harder tuner that is using a 2fast (???) bbk, ported the case and cylinder, claiming big power with lots of small issues though.
