Those pistons scare me. Look inside and see the steel struts cast in to them to control expansion. they are the cause of stress risers which can lead to cracked and broken skirts which can lead to engine failure.

I much prefer hypereutectic pistons for their strength and dimensional stability without the use of steel struts. Save the cast ones for a stock rebuild.
