Best Offster Rockers for RPM

I’ve traveled this road and I just curious how much cfm are you looking for??? Do you have any rocker arms now???

I think to achieve my goals I need about 300cfm by .550" lift. The Edelbrock intake port is pretty UGLY IMO especially with that pushrod pinch and bolt boss sticking out next to the bowl. My first impression on fixing the port is to smooth out the pinch and try to get rid of the re-expansion from that.
