Speedway roller rockers for small block?

Save your money man! I too years ago bought a set of pro-form aaluminum 1.5 roller tip rockers. Truns out (after using dial indicator on about 1/2 of them the raito was all over the place!!! Anywhere from 1.3 -1.42. Not a single one was a true 1.5 raito lesson learned! Got a set of comp cam's pro magnum 1.5 rollers & man that rocker swap alone woke my ol 340 up like crazy! Get what you pay for!
