[B]Which Roller Lifters to Use? [/B]

in my opinion it boils down 2 a matter of preferance. im sure both are quality products but me personally i would go with the comp cams do to they specialize more in just valvetrain products and spend countless hours R&D'ing there products as compared 2 ford raceing products wide selection of products. im sure ford spend's time R&d'ing 2.
comp or crane or any aftermarket performance comp. generally use higher quality material in makeing there products then OEM. and are more likely 2 have a higher fatigue rateing 2 withstand higher valve spring rates needed 4 modern performance cams.
