Roller cam opinions

Well I get it. I don't care how fast someone's car is. I just was venting my frustrations. I don't care about power. My car not running right ran 7.40s in the 1/8th mile and on the dyno it gained another 40 hp at the tire before exhaust valve stuck open.

I want to go roller just to make the motor more fluid and run better i have plenty of power and I lay down 1.5 60 ft short times. More power is gonna come sooner or later but I just want it to be reliable and not flatten damn lobes rollers don't flatten lobes.

Thanks for all the insight and opinions
