I went to Cam Dynamics for my custom grind roller cam and I'm very happy with it. I run power brakes so I needed something that wouls allow for enough vacuum for the power booster....My cam is .611 Intake and .545 exhaust and 245@50... I went with Morell lifters and yes you will need a bronze gear. The car ran a best of 12.1 @ 116, 4000 lb car and a 4 speed. I know it has mid 11s in her, I just have to get the suspension dialed in. Go roller and don't look back, it's well worth the extra $$$$$....and it works well on the street.
