I dont agree that the stock rockers will not handle it, Its that if memory serves me correctly, You have the heads with the non adjustable pedistal mounted rockers. And if you change the cam specs, the push rods will have to be changed to compensate for the added lift of the cam. And you should not reuse old rockers with new push rods, as they have develop a wear pattern from the old set. So ya the whole system should be updated if you change your cam profile. I dont think you need rollers, and heavy springs, I think I remember you are going for a mild build anyway, that does not make it mandatory for rollers with heay springs. Sure in the perfect world where money is free it would be great.
