crower stage 2- 2.3 duratec

On the stage 2 crower cams I know u have to run the stiffer springs with the street/strip 3/4. But do I have to run aftermarket pistons with valve reliefs? I'm trying to get the biggest cam that would work with the stock bottom end. 03 2.3 duratec, cosworth header, intake manifold and cold air are the mods cams would help the flow

Those cams should work fine with stock pistons. I have some OE PTV specs somewhere. Lemme dig em up.
