that was the group buy I was thinking about.
have you calculated what the CR will be using them as is vs. milling off the dome? (added cost)...guessing you'd want to keep your CR on the lower side if you plan on using a lot of boost.
the beauty with these pistons are they were designed for near 0 deck with stock rods. if you plan on building with aftermarket rods, there's no reason not to get the longer 7" rods and the lighter off the shelf forged pistons, which all seem like they're designed for the 7" rod.
