psssst, a lot of guys are having to wait months to get a set. You better put your order in soon or you'll be waiting a lot longer. I was lucky enough to find someone who was in an "unfortunate situation" and needed to sell them for the money. I on the other hand had the money and could pay immediatly. I still can't believe I did this. This is the single largest purchase I've made for my truck.

I'm not going to get my hopes up, I'm shooting for 420-430 rwhp and 420 rwtq. We'll see how well they work. I should have some great under the curve power as well as screaming top end with these heads. With the new heads I'll be at 10.98:1 compression even with the lq4 shortblock 
Running the comp cams simulator, it's looking like 541.6 HP @ 6500 and 484 torque at 5500RPM. Should come right out at 430 RWHP and 410 RWTQ if you subtract 20% drivetrain loss........
I have absolutely zero idea how accurate the dyno simulator is. The peak numbers sound way too high in the powerband to me. I have a hard time believing peak hp is at 6500rpm's and tq at 5500....
