A lot of them do indeed "tap" after being rebuilt following a cambelt failure - it's down to the rebuild not being done properly and damaged valves or guides being re-used (or because it was subsequently damaged being refitted and timed up again)
Everything being good these engines should be quiet and not tap, rattle or anything else.
The problem is the timing is that you can't rely on the timing hole on the bottom pulley being correct, as it's on the outer section that's bonded to the inner with rubber... which breaks up and allows the pulley to slip, leading to the timing hole being in the wrong place. Sometimes there's a mark on the inner pulley which lines up with the hole on the outer to confirm that it's good, but not always. Many a person has ruined an engine blindly trusting that hole is in the correct place...
