Has anyone ran a full ferrea valve train with jwt "wild cams" in a 300 TT? Valves, Titanium retainers, double chrome silicone springs and the spring seat locaters? I know in the domestic circles that ferrea is really good. This is old news but i just found out that they make stuff for sport compact (which i guess is where we z guys fall under but the Z car is in a class of it's own imho) Would like some feedback and opinions on ferrea. Thanks
