Supercharged 502 EFI Question

I had this happen on my 454 mag/efi's with a Whipple System. Engines had about 90 hours before blowers and about 150 with blowers. Compression check before blower installation was good. Also was getting a lot of gas in the oil. Finally lost a piston or rings on Labor Day. Going to new 502 blocks and blower pistons per the recommendation of an engine builder. What is it about "blower pistons" that make them less prone to this? Different ring groove shape, different ring geometry, what?
Still love the blowers. Going to stick with them.
