Indy Cylinder head 408 Crate motor

If you are looking at the $5,979.95 version of the engine, Ask if they will substitute the INDY LA-X Magnum heads for the same price. It will bump up the HP and Torque. Also the alumin heads they are using is the Mopar performance heads which may cause you problems with header fitment (TTI will have to build a one off if you have an early A Body).
