Metal in oil

360 LA crate motor mild cam, 9:1 Pistons / 67 Barracuda driver. Motor has 17,000 miles
I do about 2500 miles a year so I change oil yearly in November. I use Amsoil Z-Rod 10-30 / Filter is 21 micron WIX 51515
Second year since I added Magnetic Oil Plug and I’m getting fine powder paste on plug. Cut open filter and nothing really major stands out.
I’ve decided now to do 2 oil changes per year as a precaution.
Color of “ FUZZ” is gray not Bronze
Anything I can do proactively?
Is this normal Cam wear?
Oil pressure is very good at 60-80
Compression across all 8 cylinders is 165- 180
Pics of oil plugs are Nov 2023 and Nov 2024
Motor runs strong
What gives ? Normal ?
Kinda glad for the Magnet oil plug … I’d rather know.

How do you drive the car? What's your standard procedure for warming it up? Does it get driven much at constant speed on the highway or mostly around town? Short or long trips? And do you generally drive it hard winding it out with heavy throttle (after warmed up of course) or more putt-putting around?

Makes me want to get a mag drain plug for all my cars tbh, they all have high-mileage engines that are maintained well but get driven hard.
