TP Rockers with bigger cam?

[Twistedspoke100]

Ok I just got a 05 Mastiff with the TP rockers. Has anybody installed a 600 cam and bigger springs in there 117 without changing out the boxes. I am getting conflicting info, S&S says change them and TP says they are good do not change them. And if I do change the boxes, which I really do not want to, can I transfer the rockers into the new S&S boxes? Thanks for any help!

I have an 05 Mastiff. I junked the TP rocker boxes and bought the S&S. My valves were spinning in those TP. I had an S&S .600 cam installed. Really woke the bike up. But I had it bored .010 over and new S&S pistons installed, new timing chain and gears too. Makes my ‘16 SGS 103 feel like a pooch now.
