cam selection

[chickendreamer]

Hey guys, sorry for popping my nose into this discusion so late, but I am doing a complete engine rebuild and buying pretty much all of the parts new. I have so far gotten the edelbrock performer rpm heads with the 2.02 intake valves, and a e-303 cam. I have been told that I will need notched pistons and I am considering going with some forged alluminum pistons, not sure exactly what brand(any suggestions?) with approx. 10:1 compression pistons. I guess my big question is what ratio rocker arms should I go with, and what push rods? Also, are non-roller rocker arms good enough, the roller rocker arms seem nice but for the increase in cost to horsepower gain, they seem too much money. This is my first time rebuilding an engine so any words of wisdom is much appreciated.

Thanks a lot,
