I've heard that the low deck intake will be available by the end of the month. I'll get one on the dyno as soon as it shows up. The RB intake is available now from Summit but I haven't bought one since I don't have a standard port RB engine to use it on.
Andy, I got my low deck TF intake in yesterday. Ordered last week. Still have a month or so wait on the heads, but the intakes are available.
