quick search from 03 to 08 all pushrods are the same.
Intake
7.850
Exhaust
6.600
09 and newer only changes with VVT from what I see on a quick read of a search
A2Speed is saying correct length to remove any and all lifter clatter is 6.80 int and 8.1 exhaust.
I will measure mine and see what I have. I just might buy a set of pushrods. any and all comments are welcome.

Thank you
