All you have to remove is the valve cover and the timing chain tensioner. Very simple procedure.
....however....
The 2AZ-FE has solid bucket lifters so you will be alot of this.
I will try and post the procedure in the tech section. Unfortunately, I only seem to have the install directions. Removal should simply be the reverse.
Update.......
Just spoke with Dustin at Brian Crower. Expecting a call back today or tomorrow with actual specs, pricing, and availability!!!!
