I'm sure you know this, but to swap lifters you have to take the cylinder heads off. The T-rex can just be installed with stock heads. The reason they say that is because it is close on the piston to valve clearance and when you have heads that have been milled the pistons will contact the valves during operation if you have milled very much off. Just install the cam and you will be fine. It should make around 415rwhp.
