OH, your dislike of he Hyper pistons.... pistons fail for a few reasons. No matter what there made of. You just have to be on your game to start with when you use a Hyper since they will fail quicker when you abuse them/race them. Spark timing & too small of a ring gap are Notorious killers with a hypereutectic piston’s. However, it will do the same to a cast or forged piston. Then It doesn’t matter what the piston is made of. It will take up the whole damn engine.
Below my ‘67 - 318 in reasonable shape. Getting ready for a cam swap, intake and yup! Headers.
