Ron,
I bolted the head on as received (except for some Ford engine paint). I asked Dennis Piriano about doing any smoothing of the casting in the combustion chamber and he said it was unnecessary. As far as bolting to an otherwise stock engine, that is an expensive upgrade that will not perform to its full potential. If you don't provide more air flow to the combustion chamber, you will not get much improvement. If I was keeping the rest of the engine stock, I would go with the Snyder's 5.5 or 6.0 head. It will give you more torque but you won't be wasting money on flow that you are not feeding to the engine. You need to do your performance upgrades in a balanced manner. The Lion moves the spark plugs way over to the driver's side so you need to change to modern spark plug wires.
When we were dumb kids building muscle cars we would typically have too much cam and too much carb/manifold; but it sure looked cool !!! The result was usually a poor performing engine but oh, the bragging about what you had in it.
