Hey guys, I installed my 1.9 rockers... what type of noises would I hear if there is a brocken bolt or pushrod or something wrong?

I'm kind of dissapointed with the rockers, ive noticed some top end, and holds gears a bit better, But not as much as people rave on about it.. Why is this?

And this is what ive done so far:

1.9 Rockers
CAI SS Inductions
1 5/8 Pacemakers
2.5" cat back exhaust
69mm Throttle Body
Topgun leads

Thank you all.
