Pistons what to use

[Chad]

As it’s a new year. Hopefully an interesting topic... As with ongoing project. Was considering these in std size, on this 100k block just for the hell of it , if things measure up still in spec regarding bore , didn’t want to go oversized to much hassles ,, about a grand for six pistons with rings etc , Which isn’t much more than a set of oem rings from bmw. Anybody have experience of aftermarket pistons, ????
