The only part that is 30 spline on the longfields is the end of the shaft that is in the birfield. The end that splines into the spiders is still 27 spline.
Don't know if that was a typo or what but a stock front yota inner shaft is 30 splines at the side gears and tapers down to 27 at the birf. A 30 spline Long or dirty30 is 30 splines on both ends. Stock 27 spline inners break where they taper down between the birf and the machined surface that the seal rides on. The 30s don't taped down at all, and they don't break there.
