the stock pistons in your b20 don't have valve reliefs cut into the surface of the piston, meaning you can't run a really aggressive cam with those pistons because you could run into piston/valve clearance issues. the best thing to do is clay the motor and see what the clearance is before you put the engine together, and if there are issues, either modify the pistons and get it rebalanced, or just get new pistons. you can send an IM to t-bone or someone who knows from the all-motor section and ask what the biggest cam you can run before having issues are.
