This always starts a debate..bwth....once you move the pins around, then you can shoot for what ever weight you want.... most everyone wants light.
This worked for me, and has been running for along time
you can take some off the bottom of the skirt ( in my case I took a lot off)
bore out the pins some
grind some off the ends
I ended up with pistons lighter then any group Porsche list, have seen rpms into 7000 on a few occasions.
Again, please no debate here.......... worked for me
