Reusing Timing gears & Bolts

[LHooley]

Got a 1kd im rebuilding,

Stripped the motor and tossing whatever i wont need

And whilst the gears look good im wondering if its even worth reusing them on a complete engine do over.

Same goes with the bolts?

Motor only had 100,000kms but seized thanks to the toyota dealership not tightening the oil filter (Bloke i bought the motor from showed me the receipt)
