Metal Shavings - Second Oil Change

Aoa, I got my 5A-FE overhauled in november last year. During the period from november till now, the engine made a lot of tappet noise which I got fixed.
Upon the second oil change, I found metal shavings in the oil, as the plug I use has a magnet on it. Should I be concerned? The engine runs smooth ever since Irshad from Jameel Autos (recommended by @capsat) has worked on it. Overhaul was done by my friend.

How much time was spent on cleaning the machined block and head with soap during the overhaul?

I am unaware, as per him the head was "phased" properly. Should I be concerned, as per Irshad (Jameel Autos) we should make an assessment on the next oil change.

please request irshad to open up engine oil sump and add few more magnets to it, just in case.

phased?

like a person has a phase on his head?

please ask your overhauling friend to buy a bucket of soap next time he does an engine. And the correct term is "facing" the head - as in it smooths the "face" of the unit where it mates to head gasket on the block.

btw - Ive never encountered a Toyota A-FE head that needed to be faced unless someone literally overheated it like the chernobyl reactor.

If this is the literal second oil change - some metal debris is normal - it will clean out by the 5th oil change. But yes a magnet is a fantastic idea. When these engines were brand new, Toyota shipped them with a heavy duty oil filter that literally had a funny looking media in it, it would trap almost everything.
