That depends. What in particular are you trying to use them for? Are you talking magnetic drain plugs, oil filter magnets, parts picker uppers (technical names escape me there), transmission filter magnets, I mean there is a lot left to the imagination.

Most any rare earth magnet big enough for that use would work then. Ebay or Amazon will have many different types available. Use some 2-part epoxy to hold them in place.

You can also find ones with holes that could be bolted down, but there usually aren't many suitable threaded holes in an engine.

Grumpy, you might be right. A NdFeB magnet might not be stronger than a SmCo magnet at 100*C. I doubt they would permanently lose their magnetism in an engine though.

magnets are ceramic and glass hard, don,t try to drill or grind them, as they can shatter

Back in the old days with iron heads, I just laid a cheap magnet a little bigger than the drain back hole in each end of the head. Worked great and caught the valve spring debris.

Epoxying a similar one in the drain back hole on an aluminum head will work the same way.

Virtually all of the stuff you want to catch is from the valve springs.

You can overthink this.
