I have a solid roller cam in my 440 and so far I really like it. There is about 1500 hundred miles on the motor so far. I lashed The valves one time so far,but it did not need it.
Also since you asked, I think you should get a better set of heads like Indy EZs or SRs and open them up to a Max Wedge port window. That big of a motor needs a bigger head.
