As far as I knew it, the lift bolts lock the higher lift cam in place above 6200rpm.

They do not need replacing unless they have failed.

Some time ago there was concern from the Celica users of this engine that lift bolts might fail. It was on pre 2002 engines if my memory serves me correctly. The lift bolt design was altered slightly on later engines.

TBH, I've never read of anyone posting regarding a lift bolt failure in the Corolla forum and there's quite a few high mileage motors out there. If they were going to fail on a regular basis, I reckon we would all know about it by now.

Of course, with anything mechanical, you can never say never, so don't take my word for it ;)
