if you have 1.094 rods and that's what you want to use, then use them. you can get lighter than stock 1.094 pins. a couple years back I bought some from JE that were in the less than 190gr range. 190+gr are common and that's noticeably lighter than stock. pistons are going to be a factor of pump gas or race/blends and how much money you want to through at it all.
