Hock-the whole reason for going with SCE is that NO MACHINE WORK is needed, other than milling the head to provide a clean smooth surface.
Looks like no one noticed that the manufacturer of the other gaskets specifically states to maching a received groove in the block, and if you are at 1900 or above, then add the groove in the head.
Damon-the whole reason for going with the SCE is that the ring is integral with the gasket, making for a very tight seal-with the other gasket, you will still have the possibility of combustion pressures working past the ring and into the gasket.
When you layer rubber over copper, or rubber with steel, you provide a weak point for combustion pressures to erode and peel the layers apart.
I have done my research-the SCE ICS Titan will be the best gasket on the market for the 3.8L
