286Merc- flathead piston question

I know you always recommend the hy-duty pistons reds sells but it looks like the replaced those with badger pistons? have you ever used these ones or know anyone who has??

 

The Hy-Duty are Badgers. A tad heavier than some others but the tight fit and minimal thermal expansion makes them great for long bore & oil control life.

There may even be a true hypereutetic piston on the way, they are out now for Y Blocks. The Badgers are close tho.

 

cool thanks your info has always been very helpful.
