** NEW ** Trick Flow LA cylinder heads introduced at SEMA

B3 - do you know if they will be available with just the valves? I already purchased springs, retainers, keepers as I was going to get the Sidewinders from Todd at March. He's been trying to get the cores since Feb. and still doesn't know when they are coming in. So it looks like the TF's will be out first and I was planning on going with the TFs now (due to their advantages). But if they are twice the price, I still can get the Promaxx (same as sidewinder) from Jegs, with just the valves.
I'd really like to get my engine finished and in the car by the end of the year.
