A: I agree on KB pistons sucking and B: yes you are supposed to run taller covers with full rollers. I'd be pulling the lifters and checking the cam though myself, I've had what I thought was a header leak [tick tick tick] that ended up being a cam lobe going bad. Did you run break in oil or use a break in additive in the oil? If not that's a problem.
